Roll Crusher Apparatus

The Lab setup is used to crush different sample and material. Two heavy Smooth faced chilled metal rolls turning on parallel horizontal axes are the working elements of the roll crusher. A hopper is provided at the top for feeding the material. Particles of feed caught between the rolls are broken in compression and drop out below. The rolls turn towards each other at the same speed. They have relatively narrow faces and are larger in diameter so that they can nip moderately large lumps. Loading bolts are provided for safety. The maximum size of the product is approximately equal to gap between the rolls & it can be adjusted by loading bolts.
