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 Gyratory 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 Gyratory screen / sieve giving vibration in vertical and tangential plane. Increasing the vertical component of motion, this promotes turnover of material on the screen surface helping maximum quantity of under size material to pass through the Gyratory screen. Rugged Springs placed over the circular motor base amplifies the vibration.

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 weight creates vibration in the horizontal sieve plane which causes material to move across the sifter screen cloth to periphery. Increasing the top eccentric mass, increases the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the centre of mass, creating tilt on the sifter screen, giving vibration in vertical & tangential planes. Increasing the vertical component of motion, this promotes turnover of material on the sifter screen surface helping maximum quantity of under size material to pass through the Gyratory screen. The vertical motion also minimizes blinding of screen by "near size" particles.
