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.

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.

Safety is the key point for any piece of equipment, and asphalt mixers are of course no exception. What I want to share with you is the knowledge in this area, that is, the safe operation specifications of asphalt mixers. You might as well pay attention to it.

In fact, asphalt mixing stations are not uncommon in our daily lives. They are mainly a unit of equipment specially designed to mix asphalt. What we really don’t understand is the gas system of the asphalt mixing station. Only correct maintenance And operation can bring out the best production effect. So what are the faults in the gas circuit of asphalt mixing station?
The following three points are the more common gas path failures of asphalt mixing stations:

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.

Sinoroader secondary bag filter systems are guaranteed to deliver dust emission levels of less than 20 mg/m³ and enables asphalt plants to be sited in the most environmentally sensitive locations.

The asphalt mixing equipment mentioned here may also refer to an asphalt concrete mixing plant. At present, asphalt mixing equipment generally uses a complete set of equipment for mixing. So what are the benefits of using a complete set of equipment?
1. More effective.
In today’s industrial production, a complete set of asphalt mixing equipment can help improve production efficiency and ensure product quality. This is why even in a mixing plant, the equipment used is a complete set of equipment.
2. Ensure quality.
When mixing asphalt, a certain ratio is set. For this type of asphalt liquid used in different occasions, its ratio control has strict requirements. It is necessary to determine its mixing method and mixing time to ensure that the asphalt liquid is consistent with the production site. One of the advantages of a mixing plant is that the quality can be effectively controlled.
3. It can be sampled.
After mixing at the mixing plant, the quality inspector can sample and inspect to ensure that the mixed asphalt liquid meets the use requirements.
In short, asphalt mixing equipment will use a complete set of equipment, mainly to facilitate the later asphalt to meet production needs. Through the mixing plant, the mixing time and feeding sequence can be better controlled, so that the mixed product can meet different use requirements. And after using the archiving equipment, effective spot checks can be carried out, which can better ensure that the quality meets the construction requirements.

The environment-friendly vibrating screen supporting the asphalt plant adopts the driving mode of reverse self-synchronous operation of two vibrating motors, which has better stability. One end of the screen is fixed by a positioning pin and the other end is tensioned by a hook plate. Its unique screen fixing form makes the screen replacement very convenient and quick.

In recent years, asphalt pavement has dominated highway surfaces. With the rapid development of our country’s national economy, highway traffic volume is increasing, axle loads are increasing rapidly, vehicle speeds are increasing, and there are more and more quality problems occurring on asphalt pavements. Some are damaged after repair, and some have a service life of up to Less than design age. This has put forward increasingly higher requirements for the quality of asphalt pavement, and an important factor affecting the performance of asphalt surface layers is the gradation composition of the mixture. This article discusses the mix design of asphalt mixture.

Asphalt mixing equipment is also divided into fixed and mobile types. There are still big differences between the two to a certain extent. Let’s take a look at the design of mobile asphalt mixing equipment. What advantages can bring to the equipment?

The quality of the asphalt mixing plant will be a key factor affecting the quality of the project. After reviewing relevant materials related to the production and construction of asphalt concrete, we summarized some cases of failures in asphalt concrete mixing stations during construction and analyzed the reasons.
1. Unstable output and low production efficiency of asphalt mixing plants
(1) Improper proportioning. The mix ratio of asphalt concrete is divided into target mix ratio and production mix ratio. Among them, the target mix ratio controls the cold material transportation ratio of sand and gravel materials, and the production mix ratio is the mixing ratio of various types of sand and stone materials in the finished asphalt concrete materials specified in the design. The production mix ratio is determined by the laboratory, which directly determines the off-site grading standard of the finished asphalt concrete. The target mix ratio is set to further ensure the production mix ratio, and can be adjusted appropriately during production according to the actual situation. When the target mix ratio or the production mix ratio is not appropriate, the stones stored in each measurement of the asphalt mixing station will be disproportionate, with some overflowing and some other materials, unable to be weighed in time, and the mixing cylinder will be idling, resulting in reduced output.

As an important production equipment in construction, asphalt mixing plant has high production investment. Therefore, production is very important during use, but daily maintenance is also very important. In addition to regular maintenance, routine maintenance is also essential. The editor of Asphalt Mixing Plant shares some key points of daily maintenance and scheduled maintenance;

Asphalt mixing plant refers to a complete set of equipment used for batch production of asphalt concrete. Its main function is to produce asphalt mixture, colored asphalt mixture, etc., and has been widely used in road construction. However, during the production process of asphalt mixture, pollutants such as noise, dust, and asphalt smoke will be produced, seriously polluting the environment and threatening the health of workers. Therefore, under the current background of building a resource-saving and environment-friendly society in our country, it is very important to save energy and reduce consumption during the use of asphalt mixing plants. The following article mainly starts from the three factors that affect the asphalt mixing plant, and explores the energy saving and consumption reduction measures of the asphalt mixing plant, aiming to reduce the cost of asphalt production and improve the efficiency of the asphalt plant.

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.

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

Asphalt mixing stations play an important role in road construction. This article starts from the site selection, commissioning, and acceptance of the asphalt mixing plant, and elaborates on comprehensive and reasonable planning to avoid disturbing the normal construction order.

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.

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.

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.

As a special equipment, standardizing the operating procedures of important production tools of asphalt mixing stations, conducting daily maintenance, regular inspections, eliminating hidden dangers, etc. can effectively ensure the safety and stability of the equipment and prevent equipment from malfunctioning due to misoperation. causing equipment damage. Good maintenance operations can also greatly extend the service life of asphalt mixing plants. Therefore, before daily operation, the asphalt mixing plant must be properly maintained to make the asphalt mixing plant operate better and create wealth.

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.

Judging from the current situation of domestic highway construction, asphalt mixing stations will also achieve great development for a long time to come. This is also a result of rapid economic development. However, we have found that more and more quality problems occur when constructing asphalt pavements in modern times. Therefore, we have to put forward more stringent requirements for the quality of asphalt.

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.

Electrical control system

Asphalt mixing station is the standard for mixing asphalt. Having said that, many people still think that this has nothing to do with us. We don’t use asphalt, but do you know that our roads are made of asphalt? When I was a child, I used asphalt to pluck pig hair. The hair on the pig’s head was indeed clean. When using asphalt, it must be burned hot, because if it is cold, it will be very hard and cannot be used. Therefore, if a large amount of asphalt is needed, there must be an asphalt mixer because there is no more convenient equipment than it.
What kind of source material is asphalt that requires special equipment. Asphalt is a black-brown, high-viscosity organic liquid composed of hydrocarbons and non-metallic substances of different molecular weights. The surface is black and soluble in carbon disulfide. At the same time, it is also a waterproof, moisture-proof and anti-corrosion organic gelling material. It can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads.
