How to choose a suitable circular vibrating screen?

Circular vibrating screen is a screening device for material crushing, and its working efficiency also affects the overall efficiency of the sand production line. There are many types of vibrating screen equipment on the market, and the screening efficiency and use value are different for different types. So how to choose a circular vibrating screen?
 

1. Characteristics of screening materials

When purchasing a circular vibrating screen, the characteristics of the subsequent screening materials should be considered in advance, including the requirements for the particle size of the screened materials, the content of difficult-to-screen materials such as impurities in the materials, the water content of the materials, the appearance and specific gravity of the materials, and the clay content that is easy to paste the sieve holes.

2. Performance of circular vibrating screen

The screening efficiency of the circular vibrating screen is closely related to the screen area, number of layers, shape, size and area ratio of the sieve holes, as well as the movement mode, vibration frequency and amplitude of the vibrating screen. Generally speaking, the moving screen can make the particles of the screened material shake on the screen surface in a direction close to the vertical screen hole, increase the vibration frequency of the material, high screening efficiency, and better screening effect; the fixed vibrating screen is the opposite, making the screening efficiency low and the effect poor.

3. The use of circular vibrating screen

According to the occasions where the vibrating screen is used and the role it plays in vibration, different types of vibrating screens are selected. Usually, circular vibrating screens are used for pre-screening of materials; large circular vibrating screens, probability screens, etc. are used for grading and screening of materials after primary and secondary crushing; linear vibrating screens are used for dehydration and other media removal treatments of materials; probability screens are used for mud removal and sand removal of materials.

4. The need for crushing technology

When choosing a circular vibrating screen, it is also necessary to consider the overall capacity of the sand making production line, screening method, screening efficiency, and the inclination angle of the circular vibrating screen installation. Under the premise of meeting the requirements of particle size and output of machine-made sand products, non-metallic screen surface with larger screen hole size, larger efficient screening area, suitable screen hole shape and high screen surface opening rate should be selected as much as possible. At the same time, the installation angle of the circular vibrating screen should be adjusted to 15 degrees. This can effectively improve the effect and efficiency of screening materials.
