Gyratory Screen Separator/Vibro Shifter

Vibro shifters are circular screen separator, ideal for solids/solids and solids/liquids applications. Gyratory screen separator consists of specially designed motor mounted vertically at the center of the base plate of the screen. The screen is in between feeding hopper and bowl. The material is fed on to the center of top screen. The undersize material passes rapidly through the screen during its travel to the periphery. The over size material get continuously discharged through a tangential outlet. Specially designed vibratory motor along with eccentric top and bottom weights achieves this. They handle a wide variety of feed rates and consistencies, maximize throughput by efficient screen utilization and anti-blinding devices.

Working Principle:

The motivation is through an unbalanced motor with a double extended shaft, fitted at both ends with eccentric weights .The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weights creates vibration in the horizontal plane, which causes material to move across the screen cloth to periphery increasing the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the center of mass creating tilt on the screen giving vibration in vertical and tangential plane. Increasing the vertical component of motion, this promotes turn over of material on the screen surface helping maximum quantity of undersize material to pass through the screen. Rugged Springs placed over the circular motor base amplifies the vibration.
