Vibration Feeding Machine Type: Screening. Input Size: Max-Feeding 1200 MM. Processed Material: It can be used in mine, coal, stone and sand. Application: Vibration Feeding Machine is applied in building materials, chemical products, ore material and more. Way of Working 1. Vibration source of the trough vibration feeder is from exciter, the exciter is composed of two eccentric (driving and driven) shafts and gear pair. 2. The motor drives the driving shaft and then the driven shaft rotates geared by the upper gear of the driving shaft. 3. The materials will continuously flow by reversely rotating the driving and driven shafts at the same time and uniform feeding and coarse screening can be achieved through vibration of the body. Main Features 1. Stable vibration, reliable operation and long service life. 2. Allowing adjusting the exciting force and changing and controlling the flow at any time. 3. Low noise, small power consumption and good adjusting performance. 4. No material flushing, simple structure and easy adjustment, installation and maintenance.
