Description

Double-shaft vibrating screen

Technical Field

The utility model relates to a screening equipment technical field has especially related to biax shale shaker.

Background

The vibrating screen is efficient screening equipment and is widely applied to the fields of mining, metallurgy, water conservancy and power, buildings and the like. The vibrating screen generally comprises a screen body, a vibration exciter and a motor, wherein the motor drives a main shaft of the vibration exciter to rotate, and the screen body is driven to vibrate under the action of centrifugal inertia force generated by an unbalanced balance weight on the vibration exciter. When the vibrating screen works, the crushed material groups with different particle sizes pass through the single-layer or multi-layer screen surface with uniformly distributed holes for many times, and the process of dividing the crushed material groups into a plurality of different grades becomes screening. 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. After a large amount of crushed and 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 body, 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. The fine particles reaching the screen surface are smaller than the screen holes and pass through the screen, so that coarse and fine particle separation is finally realized, and the screening process is completed.
