Coal Mining Feeder Chains – Industrial Roller Chain
Designed for coal mining and washing systems, these chains serve as feeder, separation, and washing chains in coal pickers and washers. Built to withstand harsh mixtures of coal slime, iron, and sulfides, they offer excellent wear and corrosion resistance.
Featuring chrome-coated pins and alloy-coated sleeves, with surface hardness up to 1100HV, they ensure stable performance and long service life in demanding environments.
With 20+ years of experience, GIDI CHAIN manufactures industrial chains meeting ISO, ANSI, DIN, BS, and JIS standards, exported worldwide. We also supply chains for oilfields, agriculture, forklifts, cement, and more. Contact us for customized solutions.
