Description：● ZS series layered screen is suitable for flow operation, and is an ideal equipment for continuous discharging of particles with different sizes and proportions. ● The machine is composed of hopper, oscillation chamber, coupling and motor. The oscillation chamber is composed of eccentric wheel, rubber cushion, main shaft, bearing, etc. The adjustable eccentric weight is driven by the motor to reach the center line of the main shaft. Under the unbalanced state, the centrifugal force is generated, which changes the material strength and forms a track vortex in the screen. The amplitude of the weight regulator can be adjusted according to different materials and screens. ● The whole machine has compact structure, small size, no dust, low noise, high quality, low energy consumption, convenient movement and maintenance.
