Vibrating screening machine is composed of vibrator , screen box , the isolation device , transmission and other components , the circular trajectory inertia vibrating screen can be used for a variety of screening operations , the material constantly flipping and loose , with the following characteristics :Fine grade material has the opportunity to move to the lower part of the material layer and discharge through screen mesh.For those material Stucked in the mesh can jump out to prevent the mesh clogging ;high screening efficiencyCan change the inclination angle, change the speed of movement of the material thereby increasing the capacity.For difficult sieved material can make the spindle reversal , so that the vibration direction contrary to the direction of material movement , in order to improve the quality of screening .
