Vibro screen are driven by vertically mounted vibratory motor having eccentric weight at the top and bottom end of the shaft.at the time of motor rotation top weight causes vibration in horizontal plane where as the rotation of bottom weight causes ...

Read morelinear Vibrating Screen. linear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track ...
