The Vibrating Feeder (Vibratory feeder) is used to transfer the large size materials and granular materials from Silo to receiving device uniformly, periodically and continuously in the production flow and to feed materials into the crusher continuously and uniformly also to screen the materials in the sandstone production line. The Vibrating grizzly Feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc. Ore vibrating feeder can feed block or granule materials from the material storage to charging device evenly and continuously. It can realize even feeding for crushers in sandstone production line and make rough screening for materials. Widely applied in combined operation of crushing and screening in the industries like metallurgy, mine, mine ion, building materials, chemicals, etc.
