chain conveyor
chain conveyor
A conveyor comprising one or two endless linked chains with crossbars or flights at intervals to move the coal or mineral. The loaded side of the conveyor runs in a metal trough, while the empty side returns along guides underneath. The material is transported on the conveyor partly by riding on the chain and flights and partly by being scraped along in the trough. The chain conveyor is widely used in coal mines, and capacities range up to 100 st/h (90.7 t/h) with lengths of about 100 yd (91 m).
