The high frequency (1500 – 7200 rpm) and low amplitude (1.2 – 2.0 mm) characteristics leads to the vertical-elliptical movement that rapidly transports oversized particles down the screen.[9] Creating a thin bed of particles, this improves the efficiency and capacity of the screen. The movement pattern of a particle down a vibrating screen.
In previous researches, the average velocity of particles during the steady state of screening process was usually employed for evaluating the processing capacity of a vibrating screen, and the larger transport velocity of particles indicated the greater processing capacity (Wang et al., 2018, Yin et al., 2016, Zhao et al., 2017). From …
High-frequency vibrating screen is usually operated at an inclined angle 0°-25°, up to 45°, and the operating frequency range is 1500-7200r/m. 7. Grizzly Screen. Grizzly screen is often used for pre-screening before coarse and medium crushing of materials. The mesh size is generally >50mm, but sometimes <25mm.
