Linear vibrating screen is the use of vibration motor excitation as the vibration source, so that the material is thrown up on the screen.At the same time for linear motion forward, the material from the feeder evenly into the screen machine feed port.Through the multi-layer screen to produce several specifications of on the screen material, under the screen material, which is respectively from the respective outlet discharge. With low energy consumption, high capacity, simple structure, easy maintenance, fully closed structure, no dust scattled, automatic discharge, more suitable for assembly line operation. When the vibrating screen works, the two motor synchronous reverse rotation of the vibrator generated reverse vibration force, forcing the screen body to drive the screen to do longitudinal motion, so that the material on the vibration force and periodic forward throw a range, so as to complete the material screening operation.
