The depth of the vibrating screen bed is actually related to the size of the material. Because different sizes of materials need different depths of the sieve bed, to match, in order to achieve the best efficiency. The material and size of the vibrating screen are not the same. Generally larger materials will block smaller materials, resulting in a limited flow of materials to the lower layer.
If the bed is deep, reduce the mesh holes when the mesh size is too small for the material passing through the wire. The material bed should not be allowed to reach the surface end of the screen that prevents layering before the wire mesh discharge resulting in too small a size.
Generally, the depth of the vibrating screen bed cannot exceed three times its size, and the surface aperture of the wire mesh for screening is 100 lb. Per cubic foot of material, or three times as much as 50 pounds per cubic foot
The bed depth of the shaker will affect the efficiency and performance of the shaker. The supply end of the screen surface is overloaded, but the rest of the screen surface is spread thinly with the material.
The depth of the vibrating screen bed and the supply speed and the inclination of the screen are critical to the operation of the screen. Too thick or too thin will not work, which is a strict requirement, because if the bed is too thick, it tends to delay layering and slow down the speed. A bed that is too thin reduces efficiency because it allows the particles to move unrestricted across the screen surface.
The feeding quantity determines the service life and output of the equipment. Because the single-layer vibrating screen only deals with one kind of material, so the feeding can be properly increased, and because the multi-layer vibrating screen at the same time to deal with a variety of materials need to pay attention to the feeding amount
