Feeder Breaker Chain
The feeder breaker chain is utilized within stationary, mobile, and crawler-mounted feeder breakers. These machines use two feeder breaker chain sections that operate parallel to each other with a cross-section/ flight between the two. Our feeder breaker chains are utilized in some of the most demanding above and underground mining applications worldwide. Made from specific steel types with particular heat treatments done to each precision component, our tier-one feeder breaker chains continue to provide clients with dependable and long-term use. Additionally, our feeder breaker chains directly interchange with other brands. We supply the standard feeder breaker type chains, threaded feeder breaker chains, and buffalo feeder breaker chains. Besides the chain, we also offer head and tail shafts, sprockets, reducers, and couplings. For additional information or to request a quote on our feeder breaker chains, contact our customer support team, and we will be happy to assist you!
Feeder Breaker Chain Options:
- Anti-Corrosive (Coated, Nickle Plated, or Stainless Materials)
- Sealed (keeps continual lubrication within the internal round parts of the chain and external debris out)
- Self-Lubricating (Cintered Oil Impregnated Bushings)
- Custom Spacing For Extended Pins
- Extra Side-Plate On Extended Pin Attachment Links
