''EFI'' Gyratory screen motion is the most effective method for screening. The heart of the Vibrating screen is its specially designed heavy-duty Energy efficiency Motor, having Un balanced weight at top & bottom end of the shaft. Rotation of Un balanced top weight causes vibration in Horizontal plane whereas the rotation of lower weight causes tilt & vibrations in vertical plane. By changing their lead angle, various spiral-screening patterns are obtained to suit different application.
