What this equipment does
Coal stockpile reclaim feeders withdraw coal from stockpiles, hoppers, or reclaim tunnels at a controlled rate. They stabilize downstream conveyor loading and support blending from multiple stockpile zones. Common feeder types include belt feeders, apron feeders, chain feeders, and vibratory feeders. Selection depends on live storage pressure, coal moisture, arching tendency, reclaim rate, and maintenance access inside tunnels or enclosed galleries.

Maintenance and Wear Notes
Maintenance centers on feeder belts or pans, skirts, drive reducers, idlers, hopper liners, and gate mechanisms. Reclaim tunnels require special attention to dust, access, and confined-space safety.
