Feeder Breaker

Feeder breaker is a conveying system which incorporates combination of scrapper chain conveyor and a pick type breaker to reduce the size of the material.

Thus a feeder breaker forms a single piece of equipment with the above mentioned combination and installed at the location. Feeder breakers are a type of surface mine crushers and used to crush Run of mine ore. It is also used as in pit crusher at mine areas. Material is fed into a feed hopper directly from Mine dumpers. The chain conveyor conveys the lumps of material through the breaker which sizes the material by the force of sharp pointed picks striking down to the material. Thus the reduced material through the pick breaker is accurately sized and conveyed further.

Feed hopper is fabricated out of steel plates and suitably lined with hard liners and sometimes grizzly bars. Chain conveyor frame is fabricated out of heavy steel built up sections. Conveyor chain is of high wear resistant alloy steel. Scrapping bars are of cast type high wear resistant alloy material. Chain conveyor is driven with either hydraulic or electric motors.

The pick breaker rotor consists of machined shaft of forged alloy steel supported on two spherical bearings on either ends. Rotor is assembled with sharp and cone shaped picks. These picks are assembled in pick holders and fixed on the peripheral surface of the rotor. The end of picks is provided with highly sharpened and hard tungsten carbide tips. Feeder breaker rotor is either hydraulic or electrically operated.
