ZSW Vibrating Feeder consists of spring supporting, funnel, vibrating system, springs and motor. The vibrating system is made up of two eccentric shafts in gears meshing by specific position, and the two gears must be meshed by previous marks when it is assembled. The two shafts are driven by the motor to rotate and produce great linear vibrating force, which making the frame vibrating on springs. Through the vibration, the materials will slip and sling on the funnel, moving forward. The smaller materials falls from the grate bars, and screening before next crushing step.
