Vibrating screens are the most important screening machines primarily used in the mineral processing industry. They are used to separate feeds containing solid and crushed stones.
1. Vibrating screen mesh shape
There are a large amount of stone powder particles in the production of machine-made sand, and the requirements for grading distribution are relatively high. It is not suitable to use rectangular and round sieve holes. Square hole sieve is generally used.
2. Vibrating screen mesh size
The choice of mesh size directly affects the quality and production of machine-made sand. The larger the size of screen, the larger the sand fineness modulus and the lower the content of stone powder.In the general sand making process, the recommended mesh size is 3.5-4.5mm.
3. Screen surface inclination angle
In order to achieve better screening efficiency and throughput of materials. According to the experience of the vibrating screen manufacturer, the inclination of the screen surface is generally about 20 °.
