Gyrotary Sieving Machines (Vibroscreen)

Operating Principle :

The top eccentric weight on the motor shaft rotates in a plane, closer to the centre of the assembly. This creates vibrations in the horizontal plane which causes the material to disperse across the screen to the periphery. Any increase in the weight will increase horizontal throw of the material.

The bottom eccentric weight rotates below the center of assembly and makes the vibrations in vertical plane. The vertical throw of the material can be managed by adjusting the bottom weight. Overall material flow pattern can be controlled by adjusting the lead angle of bottom weight.
