The vibrating screen plays an important role in the screening of coffee beans; the working principle of the vibrating screen is as follows: the crushed material groups with different particle sizes pass through a single-layer or multi-layer screen surface with uniformly distributed holes for many times, and are divided into a plurality of different grades to be screened. Particles larger than the screen openings remain on the screen surface, referred to as the oversize of the screen surface, and particles smaller than the screen openings permeate through the screen openings, referred to as the undersize of the screen surface. The actual screening process is: after a large amount of scattered materials with different particle sizes and mixed thicknesses enter the screen surface, only a part of particles are contacted with the screen surface, and due to the vibration of the screen box, the material layer on the screen is loosened, so that the gap existing originally in large particles is further enlarged, and small particles pass through the gap by a machine and are transferred to a lower layer or a conveyor. Because the small particles have small gaps and large particles cannot penetrate through the small particles, original randomly arranged particle groups are separated, namely, the particles are layered according to the particle sizes, and the arrangement rule that the small particles are below and the coarse particles are above is formed.
