Regularly check the degree of wear of the hammer head, hammer shaft, liner and other wear parts. If they are worn, they should be replaced in time to avoid damage to the casing or rotor disk. The method of defining the wear of the broken surface of the hammer: In order to prolong the service life of the hammer, when the front edge of the hammer does not reach the center line of the bottom of the hammer, it should be turned over in time to increase the usage rate of the hammer. The inspection method of wear is as follows
The balance of the rotor must be ensured when the hammer head is replaced, and the total weight of the hammer head on each hammer shaft is equal to the total weight of the hammer head on the symmetrical hammer shaft, and the total deviation must not exceed 500 grams.
The bearing is a vulnerable part of the crusher, because it wears a lot during use, so it needs regular maintenance. Regularly check the bearing temperature. Under normal working conditions, the bearing temperature rise should be within the range of 40 degrees, and the bearing temperature should not exceed 75 degrees. If it exceeds 75 degrees, the machine should be shut down in time to find out the cause and eliminate it.
When replacing the bearing, be sure to install the bearing in place. Heat the bearing evenly to about 100 degrees, and quickly install the bearing on the bearing platform, so that the outer side of the bearing inner sleeve is evenly combined with the bearing shoulder of the main shaft.
Regularly check the rotor disc for wear. For the rotor disk with wear-resistant edge protection, check whether the rotor disk edge is loose or damaged to avoid wear of the rotor disk; for the rotor disk using wear-resistant electrode surfacing, check whether the wear-resistant welding block of the rotor disk needs surfacing. It is recommended to check each shift.
When replacing the rotor, first loosen the bolts at the bottom of the bearing seat, place the bearings at both ends of the rotor in the two bearing seats, use a square ruler to measure the distance between the two ends of the rotor and the inside of the casing, and adjust the distance so that the distance between the two ends is consistent. Then adjust the position of the bearing and the bearing seat, and finally tighten the bearing base bolts. The installation direction of the rotor is that the positive wire is installed on the left side facing the inlet, and the reverse wire is installed on the right side facing the inlet.
