Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the "Beam Stage Loader or BSL", which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54" across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
