Double Toothed Roll Crusher, Roller crusher, Double Roll Crusher For Coal Breaking

Roll crusher, also known as roller crusher, belongs to traditional crushing equipment. It is mainly used for fine processing of material particles. As the main working part, the two cylindrical rollers rotate oppositely to achieve the purpose of crushing. Due to its peculiar tooth crushing structure, it is also called Teeth Roll Crusher.

The surface of thesmooth roll crushermay be smooth or textured, depending on the applications. Roll crushers used to crush rocks and other heavy-duty materials generally feature teeth or spikes along the surface of each cylinder. Smooth-faced cylinders are used to crush more delicate materials, including minerals and some metals.

The drive arrangement is free standing with the electric motors mounted on adjustable base plates.

The rolls are separately driven by two identical motors, through sets of vee belts which are connected between the gearbox pulley and the flywheels.

Bolt heads are protected from excessive wear by being counter sunk in recesses on each segment. Teeth arearranged in a staggered formation on the segments to prevent tooth on tooth impact. Tooth proportions are designed for the particular product requirements.

Each roll assembly comprises of renewable and reversible toothed segments, bolted and keyed to a robust hexagonal hub with the nuts inside the hub. Locking nuts are securely located in fabricated pockets in the drum. This enables removal and replacement of segments from the outside using only one tool (Allan Key).
