General problems of asphalt mixer reversing valve

Determining the material is a necessary stage in the design process of asphalt mixing equipment, and it is also one of the most critical links, because the material will be directly related to the use effect and service life of the entire equipment. Generally, when we determine the machine material, we usually base it on the characteristics of the working medium, and the same is certainly true for asphalt mixing equipment.

The asphalt spreading truck is an intelligent high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, heavy traffic asphalt and modified asphalt. It is used in highway construction and highway maintenance projects, and can be used for the construction of upper and lower seals, permeable layers, waterproof layers, bonding layers, asphalt surface treatment, asphalt penetration pavements, fog seals and other projects of different grades of highway pavements. , can also be used for the transportation of liquid asphalt or other heavy oil. So what are the advantages of Qiangguomeng’s asphalt spreader trucks?

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

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?

Hot Recycled Asphalt Plant is a new type of asphalt mixing plant with advanced structure, mainly producing plant-mix hot recycling asphalt

Synchronized gravel sealing is to use special equipment, namely a synchronous gravel sealing truck and bonding materials (modified asphalt or modified emulsified asphalt) to be spread simultaneously on the road surface, and then formed into a single layer through natural traffic rolling or tire roller rolling. A layer of asphalt gravel wearing layer, which is mainly used as the surface layer of the road, and can also be used for the surface layer construction of low-grade highways.

Asphalt (composition: asphaltenes and resin) tanks are divided into: intermittent and continuous functions according to the production process: initial batching of aggregates, heating and drying, screening and measurement; heating and insulation of asphalt (composition: asphaltene and resin) , transportation and measurement; transportation and measurement of filler; uniformly mix the measured aggregate, asphalt (composition: asphaltene and resin), and filler into a finished product of a certain temperature.

Asphalt mixing equipment is a large-scale equipment, so you must pay attention to safety when using it to avoid accidents. But to put it simply, if you want to truly use it safely, you must master some basic common sense. The following main things must be kept in mind.

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.

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 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.

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.

The first step in establishing an asphalt mixing station is to determine the host machine and feed batching system. Generally, the configuration is based on the project’s construction period, total amount of concrete, daily concrete consumption and other indicators. The basic principle is to meet the daily concrete consumption. Under normal circumstances, a project can only have one asphalt mixing station, or separate mixing stations can be set up according to zones, or a large mixing station can be set up together with an appropriate number of concrete transport trucks, all of which depend on the actual situation.

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.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports. This equipment is mainly used to spray different types of asphalt on the ground to meet the construction requirements of different levels of ground oil permeable layer, sticky layer, left and right permeable layer, fog permeable layer, etc.

Oscillating screen. It can screen the heated aggregate according to the design. It requires fully enclosed, double oscillating motor replacement (replacing one substance for another (mostly the strong one takes the place of the weak)) eccentric shaft oscillation, each The layer screen is easy to install quickly. The service life of the drying roller and the power part is not less than 6000h. The roller can fully use heat, the material curtain flows evenly, and the inclination is required to be adjustable.

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.

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 viscosity of the bitimen melter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitimen melter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitimen melter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitimen melter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the asphalt debarrel equipment from weaning when the moisture of th
