Construction Waste Crusher in the material broken, the roller surface will gradually wear and tear, it must ensure that the material along the length of the roller evenly into the crusher. If the feed is uneven, the roller surface will appear ring groove, the impact of the normal work of the crusher, and product size is uneven. Feeding, the feeder not only need to evenly and continuously feed, the length of the same with the length of the roller.

Construction Waste Crusher roll surface in the broken material, usually wear. So the need for frequent maintenance of the roller surface. The smooth roller crusher is sometimes equipped with a grinding wheel on the rack. When the groove or groove is present on the roll, it is possible to clean the roller surface without removing the roller surface, or directly on the roll surface Repair, which requires crusher installed surfacing device. Some smooth roller crusher with roller automatic axial reciprocating device, so that the roller surface wear evenly.

When the teeth of the crusher to a certain degree, it must be replaced or repair, so as to avoid uneven product size, increased power consumption, productivity decreased.

When the roll is worn, it will increase the discharge port, so it is necessary to adjust the movable roller. Mediation need to pay attention to keep the two rollers parallel to each other, to prevent skew. The roller is mounted on the rocker or has a hydraulic compensation device. The movable roller moves automatically to ensure that the axes of the two rollers are parallel.
