The vibratory feeders is also called vibrating feeder. Vibrating feeder in the process of production, but the massive, granular materials from the storage bin evenly, timing, and continuously give into the device, can be broken in the sand and gravel production line continuous evenly feed machinery, and carries on the coarse screening for material, widely used in metallurgy, coal mine, dressing, building materials, chemical, abrasive and other industries crushing and screening combination equipment. It has simple structure, reliable operation, convenient installation, light weight, small volume and convenient maintenance. It can prevent dust pollution when adopting a closed structure. The vibration feeder structure is simple, easy to operate, no need to be rundown, low power consumption; The amount of ore can be adjusted evenly; So it has been widely used.
