The particle size of the material is divided into easy sieving and difficult sieving. The speed and probability of the material passing through the sieve during the normal screening process of the screen machine depend on the ratio of the particle diameter, shape and sieve size. The closer the particle size is to the sieve pores, the worse the particle's ability to penetrate the sieve pores and the lower the screening efficiency.

The particle size of the material is divided into easy sieve and difficult sieve, the speed and probability of the material through the sieve during the normal screening process depends on the ratio of particle diameter, shape and perforation size. The closer the size of the particles to the perforation, the worse the particle's ability to pass through the perforation, and the lower the screening efficiency.

The particle size of the material is divided into easy and hard to screen particles. The speed and probability of the material passing through the screen hole in the normal screening process of the screen machine depend on the ratio of the particle diameter, shape and the size of the screen hole. The closer the particle size is to the mesh, the worse the ability of particles to pass through the mesh and the lower the screening efficiency.<br>
