Design plan of mobile asphalt mixing equipment

People pay more and more attention to urban construction, and the use of asphalt is increasing. The application rate of asphalt mixing station is naturally growing rapidly.
Asphalt mixing station will encounter some faults more or less during use. The most common ones are uneven wear of the supporting wheel and wheel rail. Sometimes there will be some abnormal noise and gnawing. The main reason for this is that after the asphalt mixing station has been working for a period of time, the internal drying cylinder will be subjected to high temperature, and then friction will occur between the supporting wheel and wheel rail.
The above situation will also be accompanied by severe shaking, because the asphalt mixing station will directly cause the gap between the wheel rail and the supporting wheel to be improperly adjusted under the action of the drying material, or the mutual position of the two will be skewed. When encountering this situation, the user should add grease to the surface contact position of the supporting wheel and the wheel rail after daily operation.
In addition, the staff also need to pay attention to and timely adjust the tightness of the fixing nut while adding grease, and then effectively adjust the spacing between the supporting wheel and the wheel rail, so that the asphalt mixing station can work smoothly, all contact points can be evenly stressed, and there will be no shaking.

At present, most asphalt mixing plants have different degrees of energy loss in use, and these losses have brought us serious waste. How to reduce energy consumption in these aspects and achieve efficient production?
First of all, we must first summarize which aspects have energy loss, and then we can find reasonable solutions based on these problems. Through research, it is found that there are four problems in the use of asphalt mixing plants and the production of asphalt mixtures. The content and measures are as follows:
The first aspect is the management of the pile. We can reduce the energy consumption of the asphalt mixing plant through 3 specific methods: 1. Appropriately reduce the stacking height of the pile; 2. Build an inclined pile site with a good drainage structure; 3. Build a waterproof canopy.

Asphalt mixing plant is one of the main equipment for producing asphalt concrete. It can mix asphalt, gravel, cement and other materials together in a certain proportion to obtain the products required for highway construction. In order to ensure its operating effect, the asphalt mixing plant also needs to be powered on for trial operation before it is officially put into work.
The first step in commissioning is to run a single motor and check whether the current, steering, insulation and mechanical transmission parts are operating normally. After confirming that each motor and mechanical transmission parts are operating correctly, conduct a joint trial run. During the entire process, it is necessary to conduct patrol inspections of key parts. If any abnormal noise is found, the cause should be identified and eliminated in a timely manner.

Bitumen, a black or brown petroleum-like material, has a viscosity ranging from a viscous liquid to a glassy solid. It can be obtained as a residue separated from natural deposits. Bitumen consists of hydrogen and carbon compounds with small amounts of nitrogen, sulfur and oxygen. The preparation of mixed materials for mixing with asphalt is done in several steps:
Prediction: According to the asphalt recipe, the individual components of the aggregate are weighed. Usually this is done using a belt scale, since the material must go to the next step in a continuous flow.

Certain failures cannot be avoided during the use of the asphalt mixing plant. For example, a malfunction of the cold material feeding device may cause the asphalt mixing plant to shut down. This may be due to a malfunction in the asphalt mixing plant or due to gravel or foreign matter being trapped under the cold material belt.

If asphalt mixing stations want to get approval results as soon as possible and operate normally, they must have corresponding environmental protection conditions. The manufacturer will introduce to you what environmental protection conditions asphalt mixing stations should have.
1. Low energy consumption
This is what asphalt mixing stations must meet. Under the same quantity and quality, the less energy the asphalt mixing station consumes during operation, the more it meets the requirements of environmental protection, such as low consumption of water and electricity resources.
2. Reduce pollution emissions
During the operation of asphalt mixing stations, the adverse effects on the environment should be reduced and pollutants should be better controlled, so that they can be defined as environmentally friendly asphalt mixing stations. At the same time, the requirements of site planning must be met. Whether it is the production area or the conversion area of ??wastewater and waste gas, the corresponding environmental protection requirements must be met.
3. High production efficiency
An environmentally friendly asphalt mixing station must not only reduce energy consumption and reduce the emission of pollutants during the entire production process, but also achieve good production efficiency.

Asphalt mixing plant is a very practical engineering machinery. Especially in the road construction process, it plays an irreplaceable role. Due to its importance, in addition to ensuring its own quality, the use and maintenance of the equipment must be carried out normally. Let’s learn about the daily maintenance requirements of asphalt mixing plants.

When using an asphalt mixing plant, first of all, it needs to have good stability. If it does not have good stability, then the asphalt mixing plant will not be able to meet the requirements of the project in terms of requirements or mass production. For road construction, the measurement requirements of asphalt concrete are relatively strict and precise. Only qualified asphalt concrete can make the quality of road construction meet the actual requirements. Therefore, the stability of the asphalt mixing plant is very important.

Asphalt mixing station is one of the most important equipment in processing operations, so how to build a website has become the focus of people’s attention. The editor has compiled some key points, hoping to be helpful to everyone.

Speaking of asphalt mixing plants, we are not unfamiliar with them. This is a unit equipment specially used for asphalt mixing. In fact, what we really lack understanding of is its gas system. Even the accumulated failures that often occur in the gas system of asphalt mixing plants are not very clear. Facts have proved that only by properly maintaining the various systems of the equipment can efficient production and good benefits be achieved.
The following are four types of gas system failures that often occur in asphalt mixing plants. Let’s analyze the causes of the problems behind the failures one by one.

The asphalt mixing plant contains multiple different systems with different functions. The drying system is one of them. Its main function is to heat and dry the materials to reach the temperature required for the process. In order to successfully achieve this goal, the drying system must provide a certain amount of heat.

The application of asphalt mixing plants also involves selection issues. In order to give full play to the performance of the equipment, the model of the machine is mainly determined according to the actual situation of the construction site. It sounds relatively simple, but some details still need to be emphasized.
The so-called specific conditions of the construction site first include the size of the site; secondly, the properties, specifications and working dimensions of the enterprise’s supporting equipment. It is necessary to try to do a good job in all aspects to help improve production efficiency and ensure product quality. In the case of intensive network management, the network management function of the asphalt mixing plant must also be taken into account to avoid difficulties in future upgrades.

Now on the construction site, including in some engineering construction, one of the equipment used is asphalt mixing plant. It can be said that it can be used in many ranges and fields, and it can provide certain help for my country’s infrastructure construction. Of course, in the process of use, it is necessary to do a good job in many aspects, so that the use of mixing plant can be safer and more worry-free.
1. Maintain standardized operating procedures
In fact, it is not only in the use of asphalt mixing plant, but also in the use of other equipment. It should be done well. It can be said that this mixing plant will also have certain dangers. If there is any carelessness, it may also cause great losses. Therefore, at this time, it is still necessary to pay attention to the correct specifications and follow the process step by step. Only in this way can it be used safely and other use problems can be effectively avoided.
2. Adjust the reasonable mixing ratio
In the application of asphalt mixing plant, the most important and core step is the mixing. The mixing ratio of raw materials should be within a reasonable range and completed according to actual needs. Do not add or reduce raw materials at will according to your own wishes. Such operation is not standardized. In addition, after making a good ratio, you should also pay attention to safety protection measures during operation.
Asphalt mixing plant still plays an important role. If you want to make the use of the mixing plant safer and more worry-free, you should pay more attention when using it and have a certain understanding of these precautions. Only in this way can you ensure that there will be no other problems in use and ensure the safety of the mixing plant.

The development prospects of asphalt mixing plants are very good, and the product competition on the market is also very fierce. When the equipment is used, uneven wear of the supporting wheels and wheel rails often occurs, and sometimes there are some abnormal noises and edge gnawing. The main reason is that after the asphalt mixing station has been working for a period of time, the drying cylinder is exposed to high temperature and friction occurs between the supporting wheel and the wheel rail.
Under the action of drying materials in an asphalt mixing station, the equipment will vibrate violently, which will directly lead to improper adjustment of the gap between the wheel rail and the supporting wheel, or mutual interference between the two. The position is skewed, so the operator needs to add grease to the surface contact positions of the supporting wheel and the calibrating wheel rail after every day’s work.

Asphalt mixing plants bring a lot of convenience. You should understand what asphalt is. Asphalt is a very viscous liquid with a black surface that dissolves carbon disulfide. They generally exist as asphalt and smoke tar. Asphalt appeared early in social life.

In the process of building and maintaining roads, road asphalt materials are an indispensable part. Asphalt, as a binder, can be used for various surface treatments, such as roads, parking lots, airport runways, etc. However, choosing the right road asphalt material for you is not an easy task. In this article, we will discuss how to choose the road asphalt material that best suits your needs.
1. Understand the types of road asphalt materials
First, we need to understand what road asphalt materials are available. According to the material properties and their application areas, they can generally be divided into the following categories:
(1) Conventional petroleum asphalt: It is extracted from petroleum and has strong durability and viscosity. It is often used in the surface layer of highways, urban trunk roads, etc.
(2) Modular asphalt: It is obtained by mixing conventional petroleum asphalt with other materials. It has better toughness and crack resistance. It is usually used for viaducts, large airport runways, etc.
(3) High temperature stabilizer modified asphalt: By adding high temperature stabilizers, the high temperature resistance of asphalt is increased. It is usually used in high temperature areas, such as roads in southern provinces.
(4) Polymer modified asphalt: By adding polymers, the toughness, crack resistance and durability of asphalt are increased. It is usually used in large parking lots, factory areas, etc.

During the operation of the asphalt mixing plant, the quality of the mixture is often related to its construction quality. Therefore, we need to improve the quality level of the mixture as much as possible, and the temperature of the mixture is one of the standards for the qualification assessment of the mixture. In other words, if the temperature is too high or too low, the mixture may become waste and cannot meet the needs of use.
Therefore, reasonable control of the temperature of the mixture is one of the basic conditions that must be met for the normal production of the asphalt mixing plant. Among them, the quality of the fuel will affect the temperature of the mixture. For example, if the quality of the fuel is poor, the calorific value is low, and the combustion is incomplete, it will lead to unstable heating, low temperature, and a large amount of residue will be produced after combustion, affecting the quality of the mixture. If the viscosity is large, it will also cause ignition difficulties and the temperature is not easy to control.

It is inevitable that the asphalt mixing plant will have insufficient pumping force during use. In fact, during the construction process, as long as the asphalt mixing station is operated in accordance with regulations, and the accessories are cleaned and replaced in time, the asphalt mixing plant will generally not have insufficient pumping force. Now the editor of the asphalt mixing station manufacturer briefly introduces the common solutions to insufficient pumping force of asphalt mixing plant as follows.

Emulsified asphalt equipment plays an important role in road construction, and its production quality will directly affect the quality of facilities such as roads. In order to operate it better, we need to pay special attention to the following four points when applying emulsified asphalt equipment:
1. Before spraying, the emulsified asphalt equipment must check whether the position of each valve is correct. The hot asphalt added to the emulsified asphalt equipment must reach an operating temperature of 160~180℃. For long-distance transportation or long working time, a heating device can be used for insulation, but it cannot be used as an oil melting furnace.
2. When the asphalt in the emulsified asphalt equipment is heated by a burner, the asphalt height must exceed the upper plane of the combustion chamber, otherwise the combustion chamber will be burned.
3. The emulsified asphalt equipment cannot be filled too full, and the fuel filler cap must be closed tightly to prevent asphalt from overflowing during transportation.
4. This vehicle has two front and rear control consoles. When using the front control console, the switch must be turned to the front control. At this time, the rear control console can only control the lifting and lowering of the nozzle.
I believe that through the above description, everyone will be more comfortable when using emulsified asphalt equipment in the future. As for the relevant operating matters of the equipment, I will introduce them to you here today. If you want to know more information, please pay attention to the next explanation.

Asphalt mixing plants are highly professional equipment with complex systems. It is inevitable that some failures will occur during use. So, what are the common hardware failures of asphalt mixing plants? Do you know?
(I) Because its system is relatively complex, when different components have problems, the problems caused may be different. If during the operation, it is found that the material addition of each silo is inaccurate, this problem may be due to the failure of the sensor of the asphalt mixing plant. At this time, the machine should be stopped for inspection and replaced with a new sensor if necessary. It may also be caused by the jamming of the scale bar. At this time, foreign objects should be removed in time.

Asphalt mixing plant is one of the main equipment for producing asphalt concrete. It can mix asphalt, gravel, cement and other materials together in a certain proportion to obtain the products required for highway construction. In order to ensure its operating effect, the asphalt mixer plant also needs to be powered on for trial operation before it is officially put into work.
At the beginning of the test run, first run a single motor, and at the same time check whether the current, steering, insulation and mechanical transmission parts are operating normally. After confirming that each motor and mechanical transmission parts are operating correctly, conduct a joint trial run. During the entire process, it is necessary to conduct patrol inspections of key parts. If any abnormal noise is found, the cause should be identified and eliminated in a timely manner.

The asphalt mixing plant is constructed according to a certain process, which can not only ensure the construction quality, but also ensure that the asphalt mixing plant is not damaged. Although the construction details are critical, the key skills of the asphalt mixing plant construction must be mastered.
Before the construction of the asphalt mixing plant, the top surface of the asphalt mixing plant construction range should be removed, and the dry and flat site elevation should be kept to meet the design requirements. If the ground surface is too soft, the foundation should be reinforced to prevent the construction machinery from becoming unstable and to ensure that the pile frame is vertical.

Certain failures cannot be avoided during the use of the asphalt mixing plant. For example, a malfunction of the cold material feeding device may cause the asphalt mixing plant to shut down. This may be due to a malfunction in the asphalt mixing plant or due to gravel or foreign matter being trapped under the cold material belt. If it is stuck, if it is a circuit failure, first check whether the motor control inverter of the asphalt mixing station is faulty and whether the line is connected or open.

Due to the good reliability of asphalt, more and more fields have just begun to use asphalt as raw material for daily production and processing work; such as construction, urban roads, etc. In addition, the processing plant will humanize and manufacture asphalt according to customer requirements, and will use professional technical tools for asphalt mixing work. Compared with the application of old technical equipment, the new asphalt mixing equipment has stronger technicality and efficient operation speed. In addition, the equipment will use an automatic computer operating system to reduce redundant errors and reduce the working time of operators.
In addition, the processing plant will also mix and manufacture asphalt with higher precision asphalt mixing equipment, and only a small amount of raw materials and natural materials will be used for asphalt mixing and manufacturing; and it can reasonably control the quality of goods and improve the quality of goods.
Do you master the whole process of asphalt mixing equipment? The whole working process is a fusion of stone mixing, slag micro powder mixing and asphalt mixing. You can find a lot of detailed information below.

Road construction machinery is a large range, so let’s talk about one of it, which is the asphalt mixing plant. It is mainly used to produce asphalt, so it is very important among road construction machinery and equipment. An important part, if the quality of the finished product is not good, it will greatly affect the quality of the road. Therefore, below, the editor will use the form of question and answer to guide you to continue learning.

Synchronous gravel sealing in road maintenance can quickly improve road driving performance, repair anti-skid performance, smoothness, etc. It is used in preventive maintenance and is also one of the methods of low-grade road pavement construction. Synchronous gravel seal has the advantages of high strength, rough surface, non-slip, impermeable, good durability, and prevention of water mist when driving on rainy days. The so-called synchronous gravel sealing layer is to use special equipment, namely the synchronous gravel sealing truck and the bonding material (modified asphalt or modified emulsified asphalt) to be spread simultaneously on the road surface, and the single layer of asphalt wear is formed by natural driving or rolling with a road roller. layer, mainly used as asphalt surface layer.

Asphalt mixing equipment has a special function, which is that it can perform cyclic heating to make the asphalt product reach the best condition. But how does it achieve this function? Everyone is curious about this.

Asphalt mixing stations, also known as asphalt concrete mixing stations, can produce asphalt mixtures, modified asphalt mixtures, and colored asphalt mixtures, which fully meet the needs of building highways, grade roads, municipal roads, airports, ports, etc. Changmeng Electric Power introduces the safety operating procedures of asphalt mixing plants below:
1. During the operation of the mixing equipment, in addition to ensuring that the equipment is in good condition, it should also be equipped with a mineral moisture content detector and a finished material tester, and the relevant data should be frequently tested for the operator to adjust the operation in time to keep the equipment in good condition.
2. In addition to affecting production capacity, the moisture content of mineral materials is also the main factor determining fuel consumption. Additional material sheds should be added.
3. Before operation, all working parts and devices of the mixing equipment should be fully checked to see if they are intact and normal. If there are any problems, they must be properly handled before operation, and it is forbidden to operate with illness.
4. The operation must be carried out strictly in accordance with the procedures and precautions specified in the instruction manual. After normal ignition, the dust collector should be monitored to ensure that the drying drum burns under negative pressure; after production starts, the hot material elevator and agitator should be monitored to see if they are working normally to coordinate the operation of other parts.
