Vibro Screen incorporates the advanced technology in screen design. The multiplane mechanical vibrations are obtained by special motor with shaft extended on both sides having eccentric adjustable weights. The motor is mounted in Vertical plane. The complete assembly of screen which allows the system to vibrate freely in multi-direction. While the upper eccentric weight on motor imparts horizontal motion. The lower eccentric weight addes to vibrations in vertical plane. The net result is high screening efficiency . The flow pattern of the powder on the surface is controlled by varying the position of bottom eccentric weight as explained later.
