Stage Loader
From RitchieWiki
A stage loader or beam stage loader (BSL) is a chain conveyor used in the longwall mining of coal that transports coal cut by a coal shearer from the shearer's armored face conveyor (AFC) to a main belt conveyor. [1] A small crusher featuring a high-speed hammer tooth roll is also incorporated into the beam loader's design to grind coal down into the size of small particles for easier transport.[2]
