Simulation of the screening process on a

01-09-2011  Vibration parameters have significant effects on the circularly vibrating screening process. Too small a vibration amplitude, a throwing index, or a screen-deck inclination angle will cause the accumulation of particles on the deck. But too large values of these parameters will also reduce screening efficiency.
