5 Deck High-frequency Screen

【5 Deck High-frequency Screen Structure】The high-frequency sizing screen mainly consists of a linear vibrator, upper screen box, feeding box, fixed frame, lower screen basket, high-frequency vibration system, upper and lower screen material collection funnels, shear springs, etc.
【5 Deck High-frequency Screen Working Principle】The high-frequency vibrating sizeris driven by two electric vibrators with opposite movement directions to drive the screen frame in a straight line. The resultant force of the two electric vibrators acting on the screen frame passes through the center of gravity of the screen frame. Therefore, the exciting force at each point on the screen frame is the same. The slurry is fed from the upper or lower part of the ore separator and evenly divided into multiple channels through the ore separator. Then it enters multiple ore feeders through the ore feeding hose. The ore feeder sprinkles the slurry evenly on the upper end of the screen surface. Due to the continuous vibration of high frequency and small amplitude, the materials on the screen surface make a continuous jump on the inclined screen surface to disperse the materials. In the process of mixing, the fine-grained materials pass through the screen hole and are called the products under the screen, while the materials larger than the screen hole make a continuous forward jump on the inclined screen surface, and finally jump out of the screen to become the products on the screen. High frequency and small amplitude vibration can destroy the surface tension of pulp and the adhesion of fine particles to coarse particles, making materials loose and layered. The screen surface adopts a polyurethane screen, with a high opening rate and good screening permeability, which can reduce and prevent screen hole blockage and improve screening efficiency.
