When manufacturing Drives® Feederbreaker chain, we have to take into consideration the harsh mining environment and how that can impact our chain. Feederbreaker chain is used to convey large rocks into the feederbreaker machine, which then crushes those rocks into finer material. As such, this product is specially designed using alloy carbon steel and special heat treatment specifications for maximum strength and wear life.
Features & Benefits
Materials
Starting with the best materials leads to higher strength and better wear life. Our manufacturing process begins with raw materials that meet exacting standards for metal grade, mechanical properties, carbon and alloy content to ensure minimization of impurities that impact tensile and fatigue strength.
Fabrication
Drives designs each component to exacting dimensional standards for optimal performance. Precision ground pins, solid rollers and bushings work in concert with linkplates to maximize the bearing area, improving fatigue life and working loads as a result.
Heat Treatment
Strict control of atmosphere, time and temperature optimize the material properties – increasing strength, durability and wear resistance.
Shot Peening
We shot peen our roller and link plates for greater fatigue strength. This adds a layer of compressive stress that helps components resist failure when exposed to repeated high loads. In addition, we press steel balls through the pitch holes in a process called ballizing – effectively optimizing bearing contact between pins, bushings and linkplates to increase chain fatigue resistance and pin retention.
Lubrication
We use a proprietary lubrication process on all lubricated chains for enhanced corrosion protection and extended wear life.
Preloading
Following assembly, all chains are preloaded to firmly seat the pins and bushings. This is to reduce initial run-in and extend the wear life of the chain.
