BEAM STAGE LOADERS (BSL)

Features ● Stageloader and crusher completely matched to AFC, both with higher capacity to prevent bottlenecks. ● Tailor-made belt tailpiece for required capacity and belt dimensions, allowing BTP to handle longitudinal and lateral entry gradients. ● Horizontal crusher for high throughput and low oper- ating costs due to double action impact elements. ● Automated chain tensioning system for enhanced chain and sprocket lifetime. As option SlackTronic available for superior chain tension management. ● Patented PowerChain technology available.

The AFC is continuously running and conveys the coal mined by a shearer or plow to the head gate, where it is transferred onto the beam stage loader (BSL) with inte- grated crusher and then onto the main belt (eventually to the surface). Main Functions of a BSL: ● Transportation of the coal from the AFC and hand- over to the belt conveyor. ● Crushing of coal blocks to smaller sizes to suit belt capability.
