Solution File Stationary Feeder-Breakers for Surface Mining Feeder-Breaker crushes phosphate ore for conveyor belt transport at a rate of 2,000 TPH. The Joy Feeder-Breaker performs three important functions in a stationary installation: provision of surge capacity that allows the discharge of mined material at the maximum capacity of the haulage equipment, reduction of the mined material to a consistent, easily-handled size, and discharge of the fractured material at a consistent, steady rate. • Lower capital cost • Lower profile allows most haulage equipment to discharge directly into the feeder hopper. When using trucks, the elevation ramp and foundation work will be simpler, quicker and lighter Equally valuable above, as well as below ground, the advantages of a FeederBreaker as a primary crusher are being recognized by coal, lignite and limestone mining and quarrying operations. In addition to surge capacity, size reduction and consistent discharge rate, the Feeder-Breaker, when compared to conventional crushers, offers these benefits: • Lower installation height – site excavation and concrete work is reduced or eliminated • Higher throughput in tons per hour • Larger lumps of material handled routinely • Fewer fines are created because material is fractured rather than crushed • Feeder-Breaker produces no eccentric motion, thus heavy reinforcement and foundations are unnecessary • Breaker drives are electro-mechanical with direct drive arrangement A surge hopper at the intake end of the Feeder-Breaker allows trucks or other haulage equipment to discharge mined material at their maximum rates. A powerful rotary pick breaker reduces mined material to a consistent size easily handled by conveyor belts and secondary crushing operations. As the mined product moves through the Feeder-Breaker, the material flow is discharged onto the conveyor at a consistent rate the belt can accept, virtually eliminating spillage, reducing wear and significantly increa
