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

First, the characteristics of screening materials
 When selecting a vibrating screen, the characteristics of the material to be sieved should be considered, including the content of the size of the material under the screen, the content of the size of the difficult-to-screen particles, the content of the material, the shape and specific gravity of the material, and the content of the clay.

Structure of vibrating screen
 When selecting a vibrating screen, factors such as the screen area, number of layers, the shape, size and area ratio of the vibrating screen, as well as the motion mode, vibration frequency and amplitude of the vibrating screen must also be considered.

 The screening efficiency of the vibrating screen is related to the form of motion 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 sieve, the particles on the sieve surface vibrate close to the direction of the vertical sieve hole, the vibration frequency is high, and the screening effect is better; if the particles slide along the sieve surface direction, the screening effect is relatively poor.

Third, screening use
According to different screening applications, you need to choose different types of vibrating screens, such as:
If the material needs to be pre-screened, a circular vibrating screen is generally used; for broken materials, a large-scale vibrating screen and a probability screen are used for grading and screening; if the material is dewatered, a linear vibrating screen is more effective. Desilting and sand-removing work are carried out on the materials using probability screens.

Fourth, the requirements of beneficiation process
 When selecting a vibrating screen, it is also necessary to consider according to the processing capacity of the production line, the screening method, the screening efficiency, and the tilting angle of the vibrating screen.

In the actual production of machined sand, it is necessary to choose the largest screen size and effective screen area according to the actual conditions and meet the requirements of the particle size of machined sand products, and select the appropriate screen shape and screen opening. Non-metallic sieve surface with high rate to improve the screening effect and work efficiency of sand and gravel material.
