mining feeder , also known as ore feeder, is one of the the indispensable machines in ore mining process especially in crushing line and sand production line. Because of its shape just like chute, it is also called chute feeder . Mineral feeding machine is mainly used to evenly and continuously convey large stone to the feeding device.
The chute feeder is suitable for concentrating, coal, chemical and other industry department; the granular and piece materials are carried into different set from the storage bin, but not suitable for carrying the concentrate power and other power material. It can be feeded massive and granular materials from storage bin and carry these materials to a variety of subject material device. According to the experience of some dressing plants, the eccentric arm is no less than 30mm for sticky ores. The groove body of Chute Feeder is about as wide 2-2.5 times as the max feeding size. The max type Chute Feeder can satisfy the feeding size of iron ore less than 500mm. The type 980*1240 Chute Feeder is the most commonly employed one. And the feeding size of it is 350-0mm. It is suitable for the feeding to Jaw crusher of 400*600.
Chute feeder not only can be set up on the ground but also lifting in the warehouse unloading ore at the mouth. Backplane make reciprocating motion, the stroke time is 20-60 times/min, stroke is 20-200 mm. Stroke may be appropriately adjusted by the driving device eccentric wheel and the eccentricity is half a stroke. According to some mill practice, the viscous minerals, eccentricity should not be less than 30 mm. Feeder trough width is about 2-2.5 times of the largest feed particle size. The largest feeder trough can meet the particle size of less than 500 mm to the iron ore mine.
