BEAM STAGE LOADERS (BSL)
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.
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.
