Single Roll Crusher Mode of Operation
The Single Roll Crusher carries out size reduction in a wedge-shaped crushing area by pressure and shearing stress. The crushing body is composed of a rotating roll and an adjustable and spring-mounted crushing plate located on the opposite side. The distance between the base of the crushing plate and the tips of the roll crusher's teeth determines the adjustable gap width, which can be varied depending on the desired product size. Any wear and tear which may occur can be adjusted via the crushing plate. Depending on the feed material and the desired product size, the Roll Crusher is equipped with either teeth or ledges. The crushing plate is equipped with a replaceable comb plate.
Single Roll Crusher Special Features
The crushing roll is firmly fixed onto the base frame of the machine. The crushing rings, shells or ledges, made of a special casting, are mounted up or bolted on the roller body of welded construction.
The crusher shaft, made of high-grade steel, is arranged in amply-dimensioned spherical roller bearings. The bearing housings are equipped with lubricated labyrinths to avoid dust and dirt penetration. To adjust the gap width, the crushing plate is set by using threaded spindles. The spring elements provide initial tension for the crushing force and serve simultaneously as overload protection. The machine can be powered either hydraulically, by belt drive or a slip-on gear motor.

Roll Crusher Operation
1 Shut off the crusher and lockout the controls before lubricating or performing any maintenance
2 Do not clean up spilled material while the equipment is in operation
3 If the crusher becomes jammed, stop the unit, lockout the crusher and manually remove the jammed material
4 Do not force oversized material farther into crushing chamber. If the roll crusher cannot crush a piece of oversized material, stop the crusher and follow the lockout procedure and break up or remove
5 Do not stand on or above the crusher during operation
6 Keep all personnel and objects clear of the area between the shear plate and the backup block during operation. If uncrushable material enters the crusher rolls, the shear washer could break causing the shear plate to hit the backup block
