Maintenance,Preserve and Upkeep of Roller Crusher

The roller crusher requires frequent maintenance of the roll surface during operation. The smooth-to-roll crusher sometimes equipped with a grinding wheel on the frame. When the roller surface grinds out the pits or grooves, the roller surface can be repaired without grinding the roller surface. The tooth plate or gear ring of the tooth facing roller crusher can be replaced or used in a U-turn. When the tooth wear to a certain extent, must be replaced or repair, or lead to broken product size is not uniform, increased power consumption, production decline. Some machines are also equipped with surfacing devices, can be directly on the machine to repair. Some of the smooth surface of the roller crusher with roller automatic axial reciprocating device, so that the roller surface wear evenly.
 

After the roller surface wear, the discharge port width increases, the need to adjust the roller (single roll crusher is to adjust the jaw plate). Adjust the need to keep the two rollers parallel to each other to prevent skew. The use of sliding bearing roller crusher, roller bearings should pay attention to the gap. The clearance between the roller bearing and the journal is usually 1 / 10000-1.5 / 10000 of the journal diameter, and the side clearance of the bearing pad is 1/2 to 1/3 of the top clearance.

In order to ensure the normal work of the crusher, you need to always check the bearing lubrication. Sliding bearings are often refueled with oil cups or periodically injected with thin oil, and rolling bearings are lubricated and sealed regularly.

In order to ensure the maximum output of the roller crusher, the feeding must be continuously distributed evenly over the full length of the roller. The discharge port should be checked regularly for any clogging and the material should be stopped before the motor stops working. When the roller becomes idling, stop the motor. If the length of the material along the length of the roll is not uniform, the roller surface not only wear faster, and the uneven wear and tear, the ore mill operation problems, there will be ring groove, the normal broken work is damaged, broken product size evenly. Therefore, in addition to the coarse crushing of the roll crusher, the medium and fine crushing roller crusher is usually provided with a feeder to ensure continuous and uniform feeding, and the length of the feeder is equal to the length of the rollers so that the feed Along the length of the roller uniform.

The reasonable maintenance and correct operation of the roller crusher can ensure long-term continuous work and reduce the parking time, only the normal management and inspection of the normal operation of the roller crusher in order to prevent failure to ensure its continuous work.
