Operating Principle

The process of screening is to divide the crushed material group with different particle sizes into several different levels through a single or multi-layer screen surface with uniform holes many times. The particles larger than the sieve hole remain on the sieve surface called the sieve surface, and the particles smaller than the sieve hole pass through the sieve hole, called the sieve surface under the sieve. The actual screening process is: After a large number of granular materials with different particle sizes and mixed thicknesses enter the screen surface, only a part of the particles are in contact with the screen surface, due to the vibration of the screen box, the material layer on the screen is loose, so that the gap between the large particles is further expanded, and the small particles take the opportunity to pass through the gap and transfer to the lower layer or the transport machine. Because the gap between small particles is small, large particles can not pass through, so the original disorderly arrangement of the particle group is separated, that is, according to the size of the particle is stratified, forming the arrangement rule of small particles at the bottom and coarse particles at the top. The fine particles that reach the screen surface are smaller than the sieve hole, and the coarse and fine particles are separated and the screening process is completed.
