Features of mobile asphalt mixing plant:

We know that the first priority in production is to ensure safety. In the process of operating equipment, staff must always pay attention to using the correct operating methods. Regarding the asphalt mixing plant, it is used to produce asphalt mixtures, modified asphalt mixtures, and colored asphalt mixtures to meet the needs of highways, graded highways, municipal roads, airports, etc.

The HMA-B series forced asphalt mixing plant can produce reliable quality asphalt in various proportions. The product technology is mature, the operation is stable, the specifications are complete, the efficiency is high, the output is large, and the finished asphalt quality is good. It is suitable for various sizes and This type of road construction project has more obvious advantages in larger-scale road construction projects and high-grade highway construction projects.

Construction safety has always been a major issue, and we cannot let any safety hazard go unnoticed. Especially the use of equipment at the construction site. Asphalt mixing stations are prone to failure. Strengthening the maintenance of this equipment is essential to ensure safe construction at the construction site, improve equipment integrity, reduce equipment failures, and ensure the quality of concrete. The role of neglect.
The composition of the asphalt mixing plant is relatively complex, so during maintenance, classified maintenance should be carried out according to the usage and functions of different parts. Maintenance content can be divided into tank maintenance, winch system maintenance and adjustment, stroke limiter adjustment and maintenance, wire rope and pulley maintenance, lifting hopper maintenance, track and track bracket maintenance, etc.

Modified Bitumen

What should I do when the reversing valve in the asphalt mixing plant fails? The editor has a trick:
1. The reversing valve cannot be reversed or the reversing action is slow, which is generally caused by poor lubrication, stuck or damaged springs, oil or impurities stuck in the sliding parts. In this regard, you should first check whether the oil mist is working normally; whether the viscosity of the lubricating oil is appropriate. If necessary, the lubricating oil should be replaced, the sliding part of the reversing valve should be cleaned, or the spring and reversing valve should be replaced.

In order to keep the asphalt mixing plant in a stable operating process, a series of adverse factors related to it must be excluded. What should be paid attention to in this process?
First of all, the selection of the delivery pump in the asphalt mixing plant must meet the requirements of asphalt pouring per unit time during construction, height, and horizontal distance requirements. At the same time, there must be a certain technical and production capacity reserve, and the balanced production capacity is preferably 1.2 to 1.5 times.
Secondly, the movement and hydraulic systems of the asphalt mixing plant must be normal, and there must be no abnormal sound and vibration to avoid large aggregates and lumps inside the equipment, otherwise it is easy to get stuck at the feed inlet of the mixing plant or be blocked due to arching. Another point is that when the asphalt mixing plant is in the same site, it is not suitable to use too many pumps and pumps from multiple manufacturers to avoid affecting its normal operation.

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.

There is also a reversing valve in the asphalt mixer, which generally does not cause problems, so I have not understood its solution in detail before. But in actual use, we encountered this kind of failure. How should we deal with it?

Due to its complexity and importance, asphalt mixing plants are more critical in road construction. Modern asphalt mixing stations have five key systems. Do you know what they are?
1. Mixing system of asphalt mixing plant
Mixing equipment is one of the key systems, why? Usually, the productivity of the mixing equipment has a great impact on the next step of construction efficiency. Most asphalt mixing plants use twin-shaft forced mixing. Since the drying drum and burner of the mixing equipment have strong overload capabilities, and in most cases, the moisture content of the mineral materials is less than 5%, this improves the productivity of the mixing equipment. provide conditions. The mixing blades of the mixer have an adjustable assembly angle and are driven by dual mixing shafts and dual motors.

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.

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 station 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.

For road construction machinery, the following is mainly about the asphalt mixer in road construction machinery equipment. Because it is the key product of Wuxi road construction machinery manufacturers, it is necessary to carry out comprehensive training and mastery, so as to ensure meticulousness and practicality, and not ignore any knowledge points.
1. In road construction machinery, is there any difference between asphalt mixing equipment and asphalt concrete mixing equipment?
The answer given by Sinoroader Group manufacturer to this question is no, that is, there is no difference between asphalt mixing equipment and asphalt concrete mixing equipment. They refer to the same type of equipment, but they are different in name. It can be said that they are two names for the same type of equipment, and there is no difference in essence.
2. During the operation of the asphalt mixer, there is a sound in the mixing pot. What’s the matter?
In the view of Sinoroader Group, there are two answers to this question. One is that the mixer arm on the asphalt mixer is not good or damaged. The second is that the wear-resistant lining in the mixer is damaged, which leads to this problem.
3. What are the dust removal devices in the asphalt mixing equipment?
In the asphalt mixing equipment, for its dust removal device, Sinoroader Group believes that the key is to use the dry ash removal method, because it can facilitate the collection of raw materials. In terms of its dust removal equipment type, there are filter dust removal equipment, centrifugal fan dust removal equipment and force dust removal equipment, etc., which can all be used well.
For the asphalt mixer and asphalt mixing equipment in road construction machinery, I believe that through the practical discussion of the above relevant content, everyone can master it well and master it, so that in practice, they can have new gains and benefit a lot from it.

Asphalt mixing equipment is equipment used to produce asphalt concrete in large quantities. Because this equipment is affected by various factors during the production process, some problems will inevitably occur after a period of use. Sinoroader Group The editor of the asphalt mixing equipment company of China Machinery Co., Ltd. will introduce to you the methods of rescuing damaged parts in asphalt mixing equipment.
Asphalt mixing equipment encounters different problems, and the solutions are also different. For example, one of the common problems of asphalt mixing equipment is that parts are worn out and damaged. The solution that needs to be done at this time is to start from the production of parts. Just start improving.

Asphalt mixing plant is also called asphalt mixture mixing equipment, which is mainly used to produce asphalt mixtures of various specifications. It is an important equipment in projects such as road construction, highway maintenance and airport runway construction. The main components of an asphalt mixing plant include cold material supply system, drying drum, screening system, weighing system, agitator, finished product silo and control system.
The workflow of an asphalt mixing plant is generally as follows:

After use, asphalt mixing equipment needs to be disassembled, cleaned, and maintained before it can be saved for next use. Not only is the disassembly process of the equipment important, but the previous preparation work also has a greater impact, so it cannot be neglected. Please pay attention to the detailed introduction below for specific content.

In the construction industry, the installation and application of asphalt mixing plants can often be seen. This kind of equipment can complete the processing process of limestone and other powder products. The equipment has a reasonable structure and high working efficiency. It can save more costs for manufacturers during the production of asphalt raw materials. Therefore, the construction and other industries now attach great importance to the application of this equipment. During the production and processing of the equipment, the staff also need to pay attention to several operating skills to ensure that the equipment can operate stably and provide more benefits for production work.

At present, the production efficiency of asphalt mixing plants in my country’s asphalt construction is far lower than the theoretical efficiency at the time of design. The low efficiency of organic waste gas treatment will not only delay the construction process and cause a waste of resources, but also the quality of the construction will not be very good. guarantee. In the construction of asphalt pavement, the main reasons for the low production efficiency of the asphalt plant are insufficient supply of mixture, resulting in loss of continuity of construction, improper equipment parameter settings, excessive overflow and other problems. Effective measures must be taken to deal with these problems, and ultimately improve production efficiency and ensure construction quality.

Asphalt damage avoidance mechanism in asphalt mixing plant
1. Asphalt operators should undergo physical examination. Anyone suffering from conjunctivitis, skin disease or allergic reaction to asphalt should not engage in asphalt work.
2. Asphalt operators must apply protective ointment on exposed parts of their skin, and a first aid kit should be provided on the construction site.
3. The factory uniforms and protective equipment of asphalt operators are stored in a centralized manner and are prohibited from being worn home or entering collective dormitories.
4. The transfer of lumpy asphalt should usually be carried out at night and on cloudy days, especially during hot seasons. Small machinery should be used for loading and unloading, and it should not be lifted and transported directly by hand.

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.

Asphalt mixing stations and equipment must implement secondary leakage protection measures. They can only be used after being plugged in and operated through the circuit breaker before use. During the trial operation, it is necessary to verify that the rotational speed of the mixing drum will be inappropriate.

With the strengthening of the trend of environmental protection and energy conservation, the environmental protection of asphalt mixing plants has gradually become the mainstream form of mixing plant development. What kind of equipment can be called an environmentally friendly asphalt mixing plant? What are the basic conditions that must be met?
First of all, as an environmentally friendly asphalt mixing plant, it must meet the requirement of using less energy consumption during use. That is to say, under the conditions of the same quantity and quality, less energy is consumed during the operation process, including various resources such as water and electricity.
Secondly, environmentally friendly asphalt mixing plants not only require less energy consumption, but also must achieve higher production efficiency, while also reducing carbon emissions in the entire production process, so as to meet the proposed low-carbon production requirements

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.

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.

Asphalt mixing plant is a relatively important complete set of equipment in people’s lives. There are many components of this equipment, such as grading machine, vibrating screen, belt feeder, powder conveyor, elevator and other parts. Plug valve is one of them, so what is the specific role of plug valve in asphalt mixing plant? This article will give a brief introduction.
The plug valve is first of all a closure or plunger-shaped rotary valve. Generally, it is necessary to rotate 90 degrees to make the channel opening on the valve plug the same as that on the valve body, or to split it to play the role of opening or closing. The shape of the plug valve in the asphalt mixing plant is generally cylindrical or conical.

When an ordinary asphalt mixing station completes the mixing operation, it will cause great pollution to the surrounding environment. In order to solve this problem, environmentally friendly asphalt mixing equipment came into being. What are the characteristics of this type of equipment?

Asphalt mixing plants are large-scale products with high professional and technical requirements, and are composed of multiple systems. Among them, asphalt tanks are also a very critical part. Whether it is manufacturing, debugging or installation, it needs to be operated according to the actual application needs of users.
In addition to the manufacturing, debugging and installation, which need to be operated by installers, the maintenance of asphalt tanks in asphalt mixing plants must also be managed by professionals. At the same time, they must strictly follow all safety rules to operate. Before operation, they must be proficient in the relevant requirements and based on the regulations and safety instructions for storing and handling hot asphalt.

Asphalt mixing stations are constructed according to a certain process, which can not only ensure the construction quality, but also ensure that the asphalt mixing station is not damaged. Although construction details are critical, the key skills of asphalt mixing station construction must be mastered.
Before the construction of the asphalt mixing plant, the top surface of the asphalt mixing station construction range should be removed, and the site elevation should be kept dry and flat to meet the design requirements. If the surface is too soft, the foundation should be reinforced to prevent the construction machinery from losing stability and ensure that the pile frame is vertical.
Then the on-site construction machinery should be inspected to ensure that the machinery is intact and assembled and tested under the premise of meeting the requirements. To ensure the verticality of the asphalt mixing plant, the deviation of the gantry guide and the mixing shaft from the verticality of the ground shall not exceed 1.0%. Asphalt mixer manufacturer.

1: The site should be located on higher ground and away from residential areas and densely populated areas.
Because part of the equipment of the mixing station is installed below the ground, in order to avoid continuous rainfall. The equipment will suffer disaster, and the changing aggregate moisture content will affect the concrete quality. Quality accidents are prone to occur. Therefore, during site construction, attention should be paid to the construction of drainage pipelines and sand and gravel quarries. With the rapid development of cities. With the continuous expansion of urban scale, environmental protection requirements will become more and more stringent. Urban roads prohibit gravel vehicles from passing, so concrete mixing plants should be built far away from urban areas.

1.During the operation of asphalt mixing station equipment, in addition to ensuring that the asphalt mixing station 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, so as 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 that determines fuel consumption. Additional material sheds should be added.
3. Before operation, all working parts and devices of the asphalt mixing station equipment should be fully checked to see if they are intact and normal. If there is a problem, it must be properly handled before operation, and it is forbidden to operate with illness.

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.
