FACE LUMP BREAKER

They are intended for preliminary breaking of large lumps moved by the face conveyor. A wide range of height adjustment of the breaking drum above scrapers allows for crushing the winning to the desired size, which prevents its blocking in the reload pouring area from the face conveyor to the bottom conveyor. The face breaker is mounted on the specially adapted connecting pan of the main drive of the armoured face conveyor. The crushing drum height is smoothly adjusted by a hydraulic cylinder.
