Vibro Shifter is for screening rigid screening device, which vibrates with screen above its center of mass. New technology shifter is giving horizontal, vertical and circular mechanical vibration. Number of screen decks and spacing frame are assembled on circular base frame. Screen is uniformly tensioned in all direction by center support. Whole mass is suspended on coil springs, which gives thrust to screening unit by its own compression and de-compression. Springs allow unit to vibrates freely and also prevent transmission of vibration on floor. Specially designed vibrating motor generates vibration. Eccentric shaft is fixed on both side extended motor shaft. Eccentric weight is rotate with motor and generates vibration of whole masks.

Know process of Shifter
Material is to be fed into upper screen deck for screening. Fine material pass from top screen and coarser remain over screen and enter it into lower deck. Over sized material do not pass through screen of deck will automatically discharge from respective discharge spout. Over size material discharge rate can be increase by increasing horizontal throw. Horizontal throw is increase by rotation of upper eccentric mass. Maximum vertical vibration is desirable for clean the screen and dislodge material. Vertical and tangential plane vibration is change by lower weight. Angular position of upper and lower eccentric weight is for control circular motion of particles in the screen for getting better screening efficiency.
