How Does A Mining Vibrating Screen Work?

Mining vibrating screen is specially designed for the screening of granular and powdery materials. It is a commonly used screening equipment in blast furnace discharge, coking plant and mineral processing plant. principle.

Working principle of ZSG mining vibrating screen

The mine vibrating screen uses two vibrating motors to be arranged synchronously in opposite directions, so that a reverse exciter generates an exciting force, which drives the screen to move longitudinally, and the upper material is periodically thrown forward by the exciting force. When the mesh size is smaller than the screen mesh, the material falls through the screen and falls to the lower layer. Due to the circular motion of the material, the material falls into the screen box to complete the work of screening the material.

Working principle of YA/YK mine circular vibrating screen

The motor rotates the eccentric block of the exciter at a high speed through the V-belt, and the running eccentric block generates a large centrifugal force, which stimulates the screen box to produce a certain range of circular motion, and the material on the screen receives the impulse transmitted by the screen box on the inclined screen surface. , resulting in a continuous throwing motion, the process of meeting the material and the screen surface makes the particles smaller than the screen hole pass through the screen, so as to achieve classification.

Working principle of trommel screen

The main structure of the trommel screen is the sieve drum. The sieve drum rotates at a certain speed, so that the material is separated from the upper and lower parts of the sieve drum, the fine material is discharged from the front and lower part of the sieve drum, and the coarse material is discharged from the end of the sieve drum.

The above are three common mining vibrating screen equipment principles.
