What this application covers
Raw coal receiving stations control the first step of coal handling. They receive variable, often contaminated coal and meter it into crushers, screens, or conveyors. Typical equipment includes truck dumps, dump hoppers, apron feeders, feeder breakers, scalping screens, dust extraction, magnets, and belt conveyors. The station must handle surges, oversize lumps, wet coal, and tramp metal.
Step by step
Truck or conveyor receiving
ROM coal enters a hopper or receiving bin.
Controlled feeding
Apron feeders or feeder breakers meter the material.
Scalping and protection
Screens and magnets remove oversize or tramp materials.
Crushing
Coal crushers reduce the material to downstream size.
Transfer
Conveyors move raw coal to storage or preparation circuits.
Technical Buying Considerations
Raw receiving stations need robust feeders and oversize protection because feed is least controlled at this point. Undersized hoppers or feeders quickly limit plant throughput.
