The quality of the ball produced by the medium coal pressure ball machine in the coal-fired equipment production line is closely related to the degree of smashing of the raw coal in the previous period. Therefore, when configuring the coal-fired equipment production line, the quality of the crusher must be taken into consideration when selecting the crusher.
Raw coal crusher operation precautions:
1. The motor must be reliably grounded during the operation of the crusher so as to avoid unnecessary accidents.
2. The crusher should be started under the empty load, and then run empty for 2 to 3 minutes. Observe that the machine has no abnormal conditions before feeding. Feed as evenly as possible, and ensure that the motor works under the rated load, always observe the bearing temperature can not be too high, if there is overheating should immediately stop the inspection, so as not to damage the bearings, spindles and so on.
3. After the feed is finished, the crusher should continue to run for 1 to 2 minutes. The materials in the standby should be crushed and discharged before shutting down.
4. When cleaning the clogging in the crushing room, adjusting the replacement hammer, the sieve and the belt, it is necessary to cut off the power supply and wait until the machine stops running to ensure safety.
5, regular inspection hammer, flat teeth with or without cracks, wear. Regular bearing refueling.
6. To avoid dust explosion, crushing operations should be spacious, ventilated, and equipped with reliable fire protection facilities.
