Structural characteristics and principle of beneficiation shaker: all shakers are basically composed of bed surface, frame and transmission mechanism. The bed surface is approximately trapezoidal or rhombic, with 1 ~ 5D degrees of inclination in the transverse direction, and ore feeding trough and water feeding trough are configured above the inclination. A bed strip (commonly known as Laifu strip) is arranged longitudinally on the bed surface, and the height of the bed strip gradually decreases from the driving end to the opposite side, and pinches out along one or two oblique lines.

The whole beneficiation shaker bed surface is supported by the frame (if it is a suspended shaker, the bed surface is lifted), and the frame is equipped with a slope adjustment device. A transmission device is arranged at one end of the longitudinal length of the bed close to the ore feeding tank, which drives the bed surface to move back and forth asymmetrically. This movement makes the bed surface have the characteristics of rapid return movement when moving forward and approaching the end, that is, the so-called differential movement.
