Vibrating Screen Types Amp; Working Principle How To
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 of the linear vibrating.
