Spillage and carryback were accumulating at the tail section of one conveyor. This area could not be cleaned without shutting down the associated ball mill (which grinds copper ore) and locking out the conveyor. Several other manufacturers attempted to solve the carryback problems with no success. The plant even constructed its own homemade cleaners which eventually failed.

Martin installed two belt cleaners on the face of the head pulley. There wasn't enough room to modify the dribble chute to accommodate any secondary cleaners so two cleaners were squeezed into a very small area.

Upon successfully installing two belt cleaners on the face of the head pulley, within one week of operation, the belt was carryback free - for the first time ever. The satisifactory results have led the plant to upgrade other belts to this dual-cleaner system. They are also considering transfer point upgrades and service arrangements with Martin Engineering.
