 The vibrating screen is one of the indispensable equipment in the sand production line, and the working efficiency of the vibrating screen also affects the production efficiency of the sand production line. As an important screening equipment, the screening effect of the vibrating screen will affect the use value of the product. Therefore, it is very important to select the appropriate vibrating screen equipment. Here are the factors to consider when choosing a vibrating screen:

vibrating screen
1. The characteristics of screening materials
  When choosing a vibrating screen, the characteristics of the sieved material should be considered, including the content of the material under the sieve, the content of the difficult-to-sieving particle, the moisture content of the material, the shape and specific gravity of the material, and the content of clay.
Second, the structure of the vibrating screen
   When choosing a vibrating screen, the screen area, number of layers, the shape, size and area rate of the screen hole, as well as the motion mode of the vibrating screen, vibration frequency and amplitude, etc. should also be considered when selecting a vibrating screen.
The screening efficiency of    vibrating screen is related to the movement form of the screen surface, so the screening efficiency of the fixed screen is low, and the screening efficiency of the moving screen is relatively high.
   For a moving screen, the vibration of particles on the screen surface is close to the vertical screen hole direction, the vibration frequency is high, and the screening effect is better; if the particles slide along the screen surface, the screening effect is relatively poor. 
3. Screening purpose
   According to different screening purposes, different types of vibrating screens need to be selected, such as:
If you need to pre-screen the materials, generally use a circular vibrating screen; for grading and screening the crushed materials, use large-scale vibrating screens, probability screens, etc.; for de-intermediation and dehydration of materials, choosing a linear vibrating screen is better; if necessary Probability screens are used for desilting and sand cleaning of materials.
Fourth, the requirements of the beneficiation process
   When selecting a vibrating screen, it is also necessary to consider the processing capacity of the production line, screening method, screening efficiency and the inclination angle of the vibrating screen.
In the actual production of machine-made sand, it is necessary to choose a larger mesh size and effective screening area according to the actual situation and meet the requirements of the machine-made sand product particle size, and choose the appropriate mesh shape and screen surface opening. Non-metallic screen surface with high rate to improve the screening effect and work efficiency of sand and gravel materials.
