What are the precautions for the inspection of the roller crusher?

The overhaul of the roller crusher is an extremely important and regular work. It should be closely coordinated with the operation and maintenance of the machine. There should be full-time personnel on duty. The feeding must be continuously and evenly distributed over the entire length of the roller. The outlet should be checked regularly for blockage, and the feeding should be stopped before the motor stops working. When the block is completely dropped and the roller becomes idling, the motor can be stopped. . If the feeding is uneven along the length of the roller, the roller surface not only wears faster, but also wears unevenly at each point, and an annular groove will appear, so that the normal crushing work is damaged, and the granularity of the crushed product is not uniform.


Therefore, in addition to the roller crusher for coarse crushing, 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 roller, so that the feeding is made. Uniform along the length of the roller. To this end, the operator should pay attention to the following:

  • (1) Pay attention to the degree of wear of the wearing parts, and pay attention to replacing the worn parts at any time;
  • (2) Before the work, the roller crusher must be started. After the rotation speed is normal, feed the machine again. The program is reversed when parking.
  • (3) Check the discharge port regularly, and if there is any blockage, it should be cleared;
  • (4) Pay attention to the bolt fastening condition of each component, and if it is found to be loose, tighten it immediately;
  • (5) The bearing temperature should be controlled, and the temperature rise should not be higher than the surrounding air by 25 to 30 °C;
  • (6) The bearing should be refueled in time, and there is no oil leakage in the bearing;
  • (7) The machine should not be overloaded, and the electrical instrument should be kept at all times;
  • (8) The plane of the undercarriage of the movable device should be removed from dust and other materials, so as to prevent the movable bearing from moving on the chassis when the roller crusher encounters materials that cannot be broken, and serious accidents occur;
  • (9) In order to reduce the dust caused by the air leakage of the crusher casing, in actual production, when the material is dry, water is often poured at the inlet of the crusher, which results in the blockage of the filter bag and the feeder of the bag filter.
  • (10) If there is impact sound during the operation of the transmission gear, it should be stopped immediately to check and eliminate it;
  • (11) The shaft of the crusher bears the full load of the negative machine, so good lubrication has a great relationship with the bearing life. It directly affects the service life and operation rate of the machine. Therefore, the injected lubricant must be clean and the seal must be good.
