Vibrating screen plays an important role in asphalt mixing station, which directly affects the quality of the output mixture, thus affecting the service life of asphalt pavement, and also affects the construction cycle of the whole highway.

Vibrating screen plays an important role in asphalt mixing station, which directly affects the quality of the output mixture, and then affects the service life of asphalt pavement, and also affects the construction cycle of the whole highway. Therefore, it is necessary to understand the relevant common sense of vibrating screen in the operation process of asphalt mixing station. Green Machinery has been focusing on the field of vibration screening for more than ten years.Asphalt mixing plant vibrating screenWe have accumulated rich technical experience in sub-equipment and share some relevant industry knowledge with you.
The vibrating screen is like a quality inspector in the whole asphalt mixing plant system, which controls the particle uniformity of the material through top-down screening adjustment, so that the output material is more in line with the needs of the project. The screening speed of the vibrating screen directly affects the efficiency of the mixing station, and what are the factors that affect the efficiency of the vibrating screen of the asphalt mixing station?
1. Sieve surface inclination angle. When asphalt is mixed and laid, the asphalt is moved and screened on the vibrating screen surface, and the inclination angle between the screen surface and the horizontal plane will directly affect the working efficiency of the asphalt mixture mixing equipment. With the increase of the inclination angle, the movement of asphalt on the screen surface of the vibrating screen is promoted, and the transportation of asphalt is accelerated. With the decrease of the inclination angle, the movement time of asphalt on the screen surface of the vibrating screen will become longer, resulting in the reduction of productivity. Therefore, the scientific screen surface angle is very important for the vibrating screen and the whole asphalt mixing station system.
2, the nature of the sieve surface and its structural parameters. For bitumen, sieve productivity and screening efficiency are determined by sieve size. The productivity depends on the screen surface width, and the screen surface width has high productivity; the screening efficiency depends on the screen surface length, and the screen surface length has high screening efficiency. The larger the effective sieve area (I. e., the ratio of the sieve area to the entire sieve surface area), the higher the productivity per unit area and the screening efficiency of the sieve surface.

 

 

3. Amplitude and frequency. The greater the amplitude of the vibrating screen, the higher the height of the asphalt material movement, which is conducive to the penetration and sequential stratification of asphalt; high vibration frequency will increase the number of jumps of asphalt materials on the vibrating screen, which can increase the opportunity of materials through the screen surface and increase the working efficiency of the vibrating screen of asphalt mixture mixing equipment.
Good vibrating screen equipment comes from its functionality and almost harsh quality. Take Green Machinery as an example, the company has been doing the upgrading of screening equipment in recent years. InAsphalt mixing plant vibrating screenIn terms of products, the company adopts vibration motor drive, environmental protection and energy saving, basically maintenance-free, the screen is made of high manganese steel, and the screen body is sealed as a whole, which is more energy-saving...
Some companies are used to sticking to the rules and believe that maintaining the status quo can also maintain the current development of the company. The result is that five years and ten years have passed without much change, and they can only rely on price wars to survive. For the vibrating screen industry, price war and "mechanical pension" is not desirable, the development of the industry, we can be better. Therefore, we must plan ahead and seek progress in stability in order to .. The foundation of the enterprise will last and develop in the long run.
