How to choose a circular vibrating screen to ensure efficiency?

The circular vibrating screen is a screening equipment for material crushing and plays a transitional role in the sand making process. Its working efficiency also affects the overall efficiency of the sand making production line. There are many types of vibrating screen equipment on the market, with different types of models and different screening efficiency and use value. How to choose a vibrating screen to ensure the efficiency of the production line?
 

Circular vibrating screen

1. Characteristics of screening materials 

When purchasing a circular vibrating screen, the characteristics of the materials for subsequent screening should be considered in advance, which roughly includes the requirements for the particle size of the material after sieving, the content of difficult-to-sieve substances such as impurities in the material, the water content of the material, the appearance shape and specific gravity of the material, and the clay content of the sieve holes that are easy to paste.

2. Performance of circular vibrating screen 

The screening efficiency of the circular vibrating screen is closely related to factors such as the screen area, number of layers of the vibrating screen, the shape, size and area ratio of the screen hole, as well as the movement mode of the vibrating screen, the vibration frequency and amplitude of the vibrating screen. Generally speaking, the moving screen can cause the particles of the material to be screened to shake on the screen surface in a direction close to the vertical screen hole, improve the material vibration frequency, high screening efficiency and better screening effect; the fixed vibrating screening will inversely make the screening efficiency lower and the effect poor.

3. The purpose of circular vibrating screen 

Different types of vibrating screens are purchased according to the occasion of use and the role it plays for vibration. Usually, circular vibrating screens are used for pre-screening of materials; large circular vibrating screens, probability screens, etc. are used for grading screens of materials after primary and secondary crushing; linear vibrating screens are used for dehydration and demediation of materials; and sludge removal and sand cleaning work are used for material removal and probability screens.

4. The need for crushing process 

When choosing a circular vibrating screen, it is also necessary to consider the overall production capacity of the sand making production line, the screening method, the screening efficiency and the inclination angle of the vibrating screen installation. When meeting the particle size and output requirements of the machined sand product, non-metallic screen surfaces with large screen size, large screen area, appropriate screen shape, and high screen pore rate should be selected as much as possible. At the same time, the installation inclination angle of the vibrating screen is adjusted to 15 degrees, which can efficiently improve the effect and efficiency of screening materials.
