Electrical-control-system-control-room-300x197.jpg .  ② on the original road surface treatment, different road needs to take different treatment methods, the newly laid asphalt pavement, its asphalt film on the thermal reflection coating adhesion has a great impact, so before coating coating needs to carry on the road surface to sweep, destroy the asphalt film, laying a longer road surface without asphalt film treatment, However, if there are stains on the road, the corresponding treatment is required..Asphalt mixing station on the admixture of concrete, in the dosage, blending methods and mixing time must be strictly controlled, can not be used because of the small number of mixed, and can not be less admixture as a saving, can not shorten the mixing moment as a speed of progress..  Coating Layer Wellness.The health time is the same as the first layer.After the wellness is over, remove the plastic mold.If the coating covers the Signpost line, it should be removed in time.When the cleanup is complete, open the traffic.First of all, our requirements for operators are that they must undergo professional technical training, and passed the qualification examination and obtained the asphalt mixing station operating documents.Secondly, an examination should also be arranged on a regular basis to check its safety awareness.The main contents of the examination are: 1, the security system, 2, the task related to the work, 3, whether the operation mode of the equipment is correct and reasonable, 4, whether the internal safety facilities are reasonable maintenance and so on.nMobile Asphalt Drum Mix Plant mixing equipment adopts modular design, including batching system, drying system, combustion system, heat lifting, vibrating screen, heat storage materials, weighing and mixing system, asphalt supply system, powder feeding system, dust removal system, finished product silo, control system and so on.In short, all the requirements for operators are in fact to ensure that our production work can be successfully completed, but also to effectively ensure the personal safety of our staff, but also to protect our asphalt mixing plant equipment as far as possible..  To sum up, the laying of thermal reflection coating on asphalt pavement can effectively protect the pavement, prevent the production of high temperature rutting disease, and effectively alleviate the heat island effect of the city.In addition, the thermal reflection coating also has the characteristics of anti-slip, wear-resistant and strong adhesion of the road surface, and has a great application space in highway surface construction..3. Requirements for construction personnel  The quality of the coating on the pavement of thermal reflection coating is not only related to pavement and environment, but also has a great relationship with the quality of construction personnel.The basic knowledge level and construction experience of the construction personnel will affect the construction quality of the coating.In the coating construction, it is necessary to distribute the personnel reasonably, to ensure the coordination and cooperation of the personnel in each position, so that the coating construction can be successfully completed..Mixing method should be appropriate, the need for hydrolysis after the use of not dry mix, the need for powdery mixing of the agglomeration can not be used, such as water reducer or aerated agent, the control of the poor will be in the concrete to present a soft solid group, in the solid concrete to form pores..3. Convenient construction  Asphalt concrete Pavement Thermal reflection coating construction technology is relatively simple, only need to evenly apply on the road to the thermal reflection coating can be, the construction speed is fast, can open road traffic for a short time, and when the coating is damaged, maintenance is convenient.In fact, for the operation of the asphalt mixing station, we must implement it with strict standards, not only to ensure the successful completion of the whole project, but also to ensure the personal safety of our staff.Therefore, in the operation of equipment, we must require operators should meet certain standards in order to be on the job, the following we will introduce the specific requirements and standards.In the working process of the whole asphalt mixing station, we need a lot of staff to complete a series of work.Among them, for the operation of the equipment need to arrange the appropriate operators to complete.In other words, the operator should meet certain requirements before the operation can be carried out.So, do you know what kind of requirements are for the operator? Let's take a look at the specific content below..4. Requirements for opening hours of traffic  Because the construction of thermal reflection coating needs to have a certain curing period, so the construction process needs to carry out traffic blockade.Pedestrians and vehicles are not allowed on the road during the traffic blockade so as not to cause damage to the coating.The general coating hardening time between 30 minutes to 6 0 minutes, the specific time depends on the specific construction, the construction personnel must ensure that after the coating is completely hardened before the vehicle and pedestrians can be released. - Comments: 0

.dryer-drum.jpg In terms of experience and needs, the necessary staffing of 1 asphalt mixing stations is: 1 webmaster, 2 operators, 2 maintenance personnel, pound and 1, logistics catering management 1, Clerk and Financial Accounting 1, a total of 8.Operators and machine repair personnel must be asphalt mixture mixing station manufacturers or professional institutions after training to be certified for induction.So, how on earth did the transformation take place? Asphalt Mixing Plant Specific transformation content includes: 1, the first used in the past for asphalt heating heat conduction oil through the oil pump and pipeline, transport to the heat exchanger, complete the heating process of fuel oil, so that its viscosity meet the requirements; 2, before the fuel oil into the nozzle before electric heating, so as to improve the combustion efficiency of fuel.In the working process of asphalt mixing station, there will be a lot of work involved, of which its fuel system is a very critical aspect.We know that the main role of the fuel system is to complete the purpose of heat exchange, to ensure that the work is carried out..  In the asphalt material factory and road construction machinery, in addition to the Jiangwan cold mixing plant was destroyed in the 1937 anti-Japanese War, the old concession area asphalt mixture mixing plant two, including hot mixing, cold mixing, mixed asphalt stick Mixing Machine 5 units, installed production capacity of a total of 88 tons/time, but the cold mixer has a fault, has been discontinued, or abnormal production, annual output of Asphalt Mixing Plants mixture only 120,000 tons.At that time, the main road construction machinery is: Heavy roller 38 units. Pumping Machine 27 units, 4 pushers, flip 1:4 units, with 1 ".  Road maintenance of large-scale workers with 26 tortoise-shaped furnaces, 2 rounds, 4 rounds of tarmac vehicles a total of 110, a variety of cricket 268. But many old or partial imperfections.In additionFor the supply of sand and asphalt sticks, 50 vehicles are available for transport trucks.The specific process is that the heat conduction oil in the fuel system needs to enter the heat exchanger first, then heat the fuel oil inside, and then return to the heat conduction oil furnace, so that the repeated cycle heating, so as to complete the asphalt mixing station for the heating process requirements..  The initial asphalt pavement is dominated by surface treatment of absorbent tar) and asphalt pavement (tarmac stone). 1920 began to gradually develop the use of factory hot mixed heat paving asphalt stick soil pavement.In 1933, the Shanghai Municipal Works Bureau began to develop the use of cold mixed asphalt mixture technology, and in view of the use of coal tar produced by Shanghai Gas Company, has done a lot of experimental research, has established a cold mixing plant in the new city center area of Jiangwan.1936 Public Concession Shunde Road asphalt mixture mixing plant and the French concession Lou Home Bay asphalt mixture mixing plant, respectively, the cold well and hot mixing plant mixed stick. Co-material equipment.In this way, the asphalt is paved. Concrete pavement, on the development of the factory mixed hot shop, factory cold mixed cold shop, factory cold mix mixing, factory hot mix mixing, and road mixed asphalt concrete stick materials used to pave the asphalt stick soil pavement.. According to the annual production of scientific and reasonable selection of asphalt mixing equipment model, the model is too large, will increase the input cost, reduce the effective use of polyurethane products efficiency, equipment model is too small, will make the output is insufficient, resulting in construction efficiency can not be improved, thus extending the operation time, poor economy, construction personnel are also prone to fatigue.Asphalt mixture Mixing stations below Type 2000 are usually used for local construction roads or municipal maintenance and repair, and more than type 3000 is used in highways or national roads, provincial roads and other large road works, etc., usually these projects are relatively tight duration. Electrical-control-system-300x197.jpg In order to meet the needs of Shanghai workers, commercial and passenger and cargo transport, road traffic tools from rickshaws, human cars, Beasts (horse) vehicles, and so on, the gradual development of the use of various types of motor vehicles, the original sand, cinder. The pavement paved with broken bricks and gravel. Also gradually for the bullet Street pavement, Wang Shi pavement, asphalt pavement, cement concrete pavement replaced.The main roads in Shanghai take up a large number of asphalt pavement, becoming the first city in China to pave the asphalt pavement.1, to ensure a sufficient amount.In the process of admixture, should continue to be stable, the amount of supply must be sufficient, so as to ensure that the solidification time is relatively uniform, and to ensure that the asphalt mixing station concrete quality, will not produce cracks and other undesirable phenomena. - Comments: 0

What are the common problems with asphalt mixing equipment - 26 Nov 2018 14:30

  Plug valve is a closed or plunger shape of the rotary valve, after rotating 90 degrees so that the valve plug channel port and valve body on the same or separated to complete the opening or closure, widely used in oilfield excavation, transportation and refining equipment, Asphalt Drum Mix Plant mixing station also need such a valve.ASPHALT-DRUM-MIX-PLANT-dhb60.jpg   The valve plug shape of the plug valve in the asphalt mixing station can be cylindrical or conical, in the cylindrical valve plug, the channel is generally rectangular, while in the conical valve plug, the channel becomes trapezoidal.According to the viscosity grade is different, the combustion oil can be divided into light oil, heavy oil two kinds, of which light oil is not required to heat can obtain a good atomization effect, and heavy oil must be heated before use, in order to ensure that its viscosity in line with the allowable range of equipment.Not only to master the characteristics of oil, but also to inspect, adjust and clean the device, in order to avoid fire and oil blockage.  Asphalt Mixing Station plug valve because the opening and closing is quick and easy, so it is very suitable for frequent operation, and it also reflects the small fluid resistance, simple structure, relatively small size, light weight, easy maintenance, good sealing performance, no oscillation, low noise and other advantages.The asphalt mixing station will use the combustion oil when it is running, but the combustion oil is divided into different grades, if the correct use is the key for us to master.The following is about the asphalt mixing station combustion oil use specification, please be sure to abide by.Usage: Asphalt Mixing station, can also be called asphalt concrete mixing station, the equipment can produce asphalt mixture, modified asphalt mixture, color asphalt mixture, fully meet the needs of building highways, grade highways, municipal roads, airports, ports and so on.  Because the movement between the sealing surface of the plug valve has a scrub effect, and the touch with the active medium can be completely avoided when fully open, it can generally also be used in the medium with suspended particles.1, the proportion of raw materials is not reasonable.Raw materials are the first step in production, if the proportion of raw materials is unreasonable, will affect the subsequent construction of the project, will also cause the construction quality decline and other problems.The target mix ratio is to control the proportion of sandstone cold material transportation, in the production should be combined with the actual situation to adjust.If it is found that there is a problem with the co-ordination, reasonable adjustments should be made to ensure the output of the asphalt mixing station.In addition, the burner switch should be turned off at the end of the work, and then the heavy oil heating.If it takes a long time to stop or cold, should switch the oil road valve, with light oil to clean the oil road, otherwise it will cause the oil road is not smooth or difficult to ignite, which is very unfavorable to the operation of the entire asphalt mixing station.Composition: Asphalt Mixing equipment is mainly composed of batching system, drying system, combustion system, hot material lifting, vibration sieve, hot material storage warehouse, weighing stirring system, asphalt supply system, powder supply system, dust removal system, finished warehouse and control system.In addition, another important feature of the plug valve when it is easy to get used to the multi-channel structure, resulting in a valve can obtain two, three, and even four different channels, which can simplify the installation of the piping system, reduce valve dosage and some of the connecting accessories required in the equipment.In the construction process of pavement engineering, because of the complicated engineering situation, there are many kinds of problems that may arise.Among them, asphalt mixing station is the key equipment in this project, therefore, should arouse enough attention.With regard to the problems that may be encountered in this, today we take a look at what they all have.For example, one of the most common problems with equipment in the construction process is the yield problem.Because this problem will directly affect the duration of the project and other aspects of the content, so after analysis found that the asphalt mixing station production instability or inefficiency may have such several reasons, now share to everyone.According to the experience of construction cases in China over the years, the operation of asphalt mixing station will be affected by many factors, in order to promote the quality of asphalt engineering, we will combine the experience of electric flat car production and construction to carry out analysis, to find the cause of some problems in the construction process, to provide you with some practical experience. - Comments: 0

Does the asphalt mixing equipment belong to the concrete machinery? - 23 Nov 2018 14:30

In addition, the third aspect of the problem is that the user should pay attention to ensure the appropriate discharge time in the course of operation.In addition, it is recommended that we prepare sufficient transport vehicles according to the production capacity and transport distance of the asphalt mixing station to ensure timely transportation so as not to affect the progress of the project.aspahlt-for-sale-LB1500-1.jpg In asphalt mixture, the main function of asphalt is to form cementation with fine aggregate and mineral powder and other fillers, promote the bonding between aggregates and improve the integrity of the mixture, so the amount of asphalt has an important influence on the rutting resistance of asphalt mixture.The first aspect is the time to feed.Therefore, if you want to improve the production efficiency of the asphalt mixing station, then the user in the process of operation will need to regularly check the butterfly valve and related electrical components, to ensure the normal operation of the entire system, and ensure the smooth connection between the powder hopper and the mixer, to ensure the normal feeding time.Secondly, the user should also pay attention to check the mixing machine internal blade liner integrity, the location of raw materials and delivery time period, etc., to ensure the appropriate mixing time.3, Asphalt mixing company introduced 4 kinds of rutting of asphalt concrete, the influence of unstable rutting on asphalt concrete pavement is relatively large, not only related to the structure combination of asphalt surface layer, but also closely connected with the selection of surface material and internal grading of asphalt surface layer.In the actual preparation process, the determination of its comprehensive performance to achieve a better amount of asphalt can generally be determined according to the Marshall Test or SGC method, but the same level of the latter than the former dosage of 0 less. 2%~0. 5%.Finally, the staff also need to regularly maintain the asphalt mixing station equipment maintenance management, so that the equipment is in the best working condition, daily maintenance in time to check the existence of safety hazards, and to eliminate, to ensure that the asphalt mixing station safe and efficient work.However, in the actual work, for the ratio of raw materials many users do not have a wealth of reliable experience.And in the asphalt mixing station work, for the raw material matching scheme is not static, need to be adjusted according to various circumstances, so, in the matching work, what to measure?Q: Some put asphalt mixing equipment into the pavement machinery asphalt concrete is concrete?A: Asphalt concrete is asphalt concrete by manual selection with a certain level of composition of the mineral (gravel or crushed gravel, stone crumbs or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, in strict control of the mixing of mixed materials.1, asphalt Mixing company introduced the proportion of coarse aggregate in the internal grading of asphalt concrete aggregate is positively correlated with the rutting resistance of asphalt concrete, but with the amount of bitumen and the voids of the mixture, the high coarse aggregate content can prevent the rutting to a large extent.We should understand that the ratio of raw materials is one of the most important and basic things in the working process of asphalt mixing station, which should take into account the actual materials used, including the stirring method of asphalt and other factors, and finally in the determination.This is because, different materials or different mixing methods, the corresponding matching scheme will have a difference, therefore, the best solution is according to the calculation ratio to carry out the ratio.In addition, the properties of the material, such as the adhesion requirements, should also be taken into account, and we can do so by adjusting the amount of water and sand rate until the mixture meets the requirements of the construction.In the use of asphalt mixer, the user must seriously consider the question of how the ratio of raw materials should be carried out.Asphalt mixer is an important equipment of asphalt mixing station, and its working condition will affect the whole construction situation.Therefore, for this issue, users must take it seriously.So far, asphalt mixing station in China has gone through a long period of development, so that, but also accumulated a wealth of production experience, technology is becoming more and more mature.In fact, we can also be very intuitive to see that the original low production efficiency has now gradually developed into a high efficiency and low energy consumption of the development characteristics.Let's take a look at the specific content together.From the above content can be learned that the Asphalt Mixing Plants mixing station market in China has also undergone many changes, and with the development of the economy and the passage of time, the market of Vortex Air pump products is also constantly heating up.However, when we build a good station, how can we operate to ensure high productivity? Next, we will discuss this issue.In fact, there are three aspects that will have a greater impact on the production efficiency of the mixing station. - Comments: 0

ASPHALT-DRUM-MIX-PLANT-dhb80.jpg 3, the discharge temperature is not uniform.As we all know, the temperature of the discharge will have an important impact on the quality of the use of the material.If the temperature is too high to live too low, will cause these materials can not be used properly to become waste, not only a serious waste of asphalt mixing station production costs, but also affect its production output.1, the proportion of raw materials is not reasonable.Raw materials are the first step in production, if the proportion of raw materials is unreasonable, will affect the subsequent construction of the project, will also cause the construction quality decline and other problems.The target mix ratio is to control the proportion of sandstone cold material transportation, in the production should be combined with the actual situation to adjust.If it is found that there is a problem with the co-ordination, reasonable adjustments should be made to ensure the output of the asphalt mixing station.According to the experience of construction cases in China over the years, the operation of asphalt mixing station will be affected by many factors, in order to promote the quality of asphalt engineering, we will combine the experience of electric flat car production and construction to carry out analysis, to find the cause of some problems in the construction process, to provide you with some practical experience.  Finally, in recent years, asphalt mixing stations have also attached great importance to independent research and development, and continue to strengthen investment in this field.Judging from the development of some large manufacturers in China, the asphalt mixing equipment industry in China must take a firm foothold in the market to follow the path of independent research and development.  The third aspect is the continuous introduction of foreign advanced technology in recent years.As we all know, China's asphalt mixing station industry started late, the experience is not rich enough, but at the same time, the Chinese market has a broad market prospects.Therefore, many enterprises and foreign enterprises in China have adopted a cooperative approach.  ① Cold Mixing regeneration  The Recycled Asphalt Drum Mix Plant Pavement material (RAP) is transported to the mixing plant (field, station).After crushing, screening, to a certain proportion with the Xinji material, asphalt regeneration binder, active filler (cement, lime, etc.), water, such as mixing at room temperature, asphalt pavement regeneration technology paved at room temperature.  First of all, the asphalt mixing station is affected by the policy.Since China's reform and opening up, many industries have entered a stage of rapid development, asphalt mixing station industry is no exception.Later, it also launched its 11th five-year development plan, which has also greatly contributed to the rapid development of the industry.Under the influence of this policy, the development of highway construction in China has developed very rapidly in the past 20 or 30 years.2, fuel combustion value is insufficient.In order to ensure the quality of construction, therefore, the quality of combustion oil should be selected and used in accordance with the prescribed standards.Otherwise, if you choose the general burning of diesel oil, heavy diesel or heavy oil, it will seriously affect the heating capacity of the drying cylinder, resulting in low production of asphalt mixing station.  ① Hot Mix Regeneration  The Recycled asphalt Pavement material (RAP) is transported to the asphalt mixing plant (field, station), which is broken and screened, and mixed with a certain proportion with the new material, fresh asphalt, regenerative agent (if necessary) and so on to make hot mix recycled mixture to pave the road surface technology.mobile-asphalt-mixing-plant-MLB700-1.jpg For example, one of the most common problems with equipment in the construction process is the yield problem.Because this problem will directly affect the duration of the project and other aspects of the content, so after analysis found that the asphalt mixing station production instability or inefficiency may have such several reasons, now share to everyone.  In the geothermal regeneration to the asphalt pavement heating, milling, in situ mixed with a certain number of new bitumen and other regenerative agents, and then through the hot state mixing, paving, milling and other processes, so the unit is many and complex, the need for a combination of multi-clock units to carry out operations, the initial equipment investment is also larger.The geothermal regeneration equipment can be divided into two kinds, such as compound mixing regeneration and resurfacing regeneration.  From the data released by the European Asphalt Pavement Association, the methods of asphalt pavement regeneration in Europe and America are mainly heat and temperature mixing, and the international Organization for Economic Cooperation and Development (OECD) survey on the recycling of pavement in 14 countries shows that (asphalt part), Hot mix regeneration (plant mixing heat regeneration) is a commonly used regeneration method, cold regeneration generally only accounts Other regeneration methods are also used in only a few countries. - Comments: 0

Common Problems of asphalt mixer - 18 Nov 2018 13:20

mixer-300x225.jpg Asphalt smoke refers to the hydrocarbon organic particulate matter emitted in the production process of petroleum bitumen and asphalt products and a small amount of gaseous hydrocarbon substances at normal temperature, it is a mixed type of flue gas containing complex chemicals, the main component is hydrocarbon mixture, of which polycyclic aromatic hydrocarbons have the most substances.Asphalt smoke contains a strong carcinogen benzene and pyrene and other polycyclic aromatic hydrocarbon substances.Polycyclic aromatic hydrocarbon substances in the atmosphere are an important cause of the rise of respiratory cancer.Pure benzene and pyrene is a yellow needle crystal, boiling point of 310 ℃, melting point 179 ℃, insoluble in water, slightly soluble in alcohol, is a strong carcinogen, can cause skin cancer, in bitumen flue gas, easy to attach to the particle size of 8. On particulate matter below 0um.According to the above analysis, it is necessary to make the transformation of the thermal conductivity oil heating system of the asphalt mixing station, including the position of the higher oil filling tank, the installation of the exhaust valve, the trimming of the conveyor pipe, and the addition of the booster pump and the insulation layer.After improvement, the temperature of asphalt mixing station only meets the requirements, and the parts are running normally.  Exclusion method: ① will bow fan from the body removed, welding repair positive and good dynamic balance, you can eliminate the noise.② with a mop to clean the leaves, remove the dust, remove the hard block.③ pay attention to bearing lubrication maintenance, timely addition of calcium base grease, if the bearing has been damaged, ablation, it must be replaced.We found that when the asphalt mixing station was operating under low temperature, because the asphalt circulating pump and spraying pump could not operate, the asphalt in the asphalt scale solidified, which eventually caused the Asphalt Drum Mix Plant mixing station to fail to produce normally.After inspection, it is proved that the asphalt in the asphalt pipeline does not meet the requirements, which causes the bitumen in the pipeline to solidify.Emma Road Construction machinery technology to provide efficient, high-performance, durable unit equipment and structure, the accuracy of each weighing unit can be improved control, can prevent environmental pollution, but not satisfactory, we also need to make every effort to develop efficient, economical and productive plants and equipment to meet the needs of all specific customers abroad.The specific reason is that there are four possibilities, one is that the high oil tank of the heat conduction oil is too low, resulting in a poor circulation of the heat conduction oil; the other is the eccentricity of the inner layer tube of the double tube; the other is that the heat conduction tubing passes long;In the process of asphalt stirring, heating is one of the indispensable links, so the asphalt mixing station will inevitably be set up with heating system.This system can malfunction under the influence of various factors, which indicates that the heating system must be modified.aspahlt-for-sale-LB700-1.jpg   Main reasons: After a certain period of work, the drying cylinder is affected by alternating load and high temperature, coupled with the drying of grease, so that the wheel rail and the wheel between the formation of dry friction, by the drying material gravity, so that the machine shaking violently, resulting in uneven force of the wheel and rail and wheel.In the above case, if the gap between the wheel and the wheel rail is improperly adjusted, or if the position of each other is skewed, it is easy to occur the above fault phenomenon.Key points of construction quality control(1) Milling material in the factory after crushing, screening into particle size 0~10mm and 10~25mm two kinds of milling material specifications.Use two cold silo to ensure a stable grading when mixing the material.(3) Absorption method It uses various mixed components in asphalt flue gas to have different solubility in the absorber, or the active component in the absorber reacts with a certain component to achieve the purpose of treating the asphalt flue gas.Generally use gasoline, diesel and other substances for absorption, this method system resistance is small, low energy consumption, simple equipment, easy maintenance, but the purification rate is not high, flammable, also not easy to adopt;(2) The principle of electrostatic capture of asphalt flue gas by electric catch method is the same as that of electrostatic precipitator, not only through the fan to send asphalt smoke into the electric field, through the yin and yang Poles, with the help of Corona discharge, so that the particles of asphalt smoke charged and adsorbed to the plate, to separate the asphalt smoke and gas for the purpose.Dry-type electric catcher for gas phase components capture efficiency is very low, and wet electric catcher can capture gaseous bitumen, but wet electrical supplements produce electric waste wastewater, resulting in two pollution. - Comments: 0

mobile-asphalt-mixing-plant-MLB1000-2.jpg   3. Market.For self-produced mixer shaft head accessories Manufacturers, of course, the price should be relatively cheap.But after multiple channels of sales, the price is bound to be expensive.After a period of time, some companies have completed the asphalt mixing station burner oil, gas dual-use technical transformation, burner and gas system total cost of 1.1 million yuan or so, the current use of good.It is expected that the production of 100,000 tons of mixing materials can directly save the cost of transformation, but it brings such as environmental protection, energy saving and many other invisible benefits are huge.It can be seen that if there are conditions for asphalt commercial concrete mixing station, it is imperative to transform the sky gas.The electrical control system adopts a distributed system composed of industrial control computer and programmable controller (PLC), which realizes the fully automatic control of the production process of the plant mixing equipment.It has the following main functions:Automatic control and condition monitoring of equipment boot/shutdown process.  2. Demand.If the demand for accessories is not very large or very popular, the merchant will also be appropriate to adjust the price of the mixer shaft head accessories According to this aspect.  Because of raw materials or the use of the reasons, asphalt mixer in the daily use of how much will be subject to a certain degree of wear or other failure, if not timely control or repair, the problem will be further aggravated.For asphalt mixers, what are the ways to prevent wear and the way to prevent failure?  Asphalt mixer After wear is not timely treatment, once with air, rainwater and other long-term contact is likely to occur corrosion, if the asphalt mixer parts corrosion is serious, the entire equipment life and normal operation will be affected.  In addition, in order to reduce unnecessary wear and tear, in the production of asphalt stirring boot can be selected with a more relaxed section to filter, but also the use of penetration, quenching and other means to improve the hardness of the parts.There is also a need to consider the effect of reducing the friction planning level when designing part shapes.Any mechanical stability and efficient work is inseparable from any of its accessories, mixer and belongs to the more high-strength work of the equipment, mixer shaft head accessories, such as the quality and performance requirements are relatively high, otherwise it will not be long before there is damage.Customers in the purchase should pay attention to reasonable selection, the price can not be very low, too high is certainly not cost-effective.Generally speaking, the price of wear-resistant accessories such as mixer shaft head fittings will be affected by several factors, and should be treated rationally when purchasing.In addition, the use of heavy oil every 100,000 tons need to replace 2 heavy oil pump, imported heavy oil pump each price of about 20,000 yuan, injector 2 sets, each set price 1. 80,000 yuan, the use of gas is basically very few mechanical parts damaged, this item can save 80,000 yuan.aspahlt-for-sale-LB4000-1.jpg Q: Some put asphalt mixing equipment into the pavement machinery asphalt concrete is concrete?A: Asphalt concrete is asphalt concrete by manual selection with a certain level of composition of the mineral (gravel or crushed gravel, stone crumbs or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, in strict control of the mixing of mixed materials.1. Quality.There is no doubt that the better the quality of the asphalt mixer shaft head fittings, the more fine the work, the higher the sales price, and the brand Merchant's products will be relatively expensive.  Lontto Machinery Co., Ltd. is specialized in road construction machinery manufacturing, research and development enterprises.Main Manufacturing: LB series, J series Asphalt mixing equipment, rap asphalt thermal Regeneration equipment, WCB series of stable soil plant mixing equipment, GLS series of asphalt modification equipment, hrs series Asphalt emulsion equipment and design, construction of large-scale asphalt transit library, etc. It can meet the needs of asphalt pavement construction and maintenance engineering in highway and municipal construction industry.  And the fault of the asphalt mixer often occurs on its commutator valve, for example, the commutator valve can not change the commutative or commutative action is slow, and most of this is due to poor lubrication, spring is jammed or damaged, oil or impurities stuck in the sliding part and other reasons.At present, mixing station using heavy oil fuel, often unable to ignite or ignition after the combustion of the Midway quenching phenomenon, resulting in a large number of stone and fuel waste, only this annual loss of about 250,000 yuan, but also wasted a lot of manpower, material resources and time, the formation of construction units urgent and other materials, Mixing station but because of burner ignition problem and can not timely supply of embarrassing situation, to the mixing station caused a very bad impact, affecting the construction schedule, a project is slow to complete, other projects can not undertake, the annual loss of the amount of work is about 20,000 tons, the loss of pure profit of about 300,000 yuan. - Comments: 0
