The importance of fastener bolts for counterattack and counterattack maintenance

Counterattack and break the frequently occurring problems:

1. If an abnormal vibration is found in the counterattack:

1. Explain that the material is too large, you can check the feed size.

2. The uneven wear indicates that the impact hammer head needs to be replaced.

3. The rotor is unbalanced and needs to be adjusted.

4. If the foundation is not handled properly, the anchor bolts need to be checked and reinforced.

2. If it is found that the counterattack breaks the bearing heat:

1. Explain that the bearing is short of oil and need to be refueled in time. Of course, too much oil will cause the bearing to heat up, so check the oil level when refueling. 2. If the bearing is damaged, replace the bearing in time.

3. If the upper cover is too tight, the bolts should be adjusted and the tightness is appropriate.

3. If it is found that the particle size of the counter-breaking material is too large:

1. It means that the hammer head is worn out, and the hammer head needs to be idled or replaced.

2. The gap between the hammer head and the counterattack plate is too large, generally adjusted to 15-20mm.

3. Excessive feeding granularity will also affect the discharging granularity.

Four. If the counterattack is now turning over the broken belt:

1. Explain that the belt is worn and the V-belt needs to be replaced.

2. Due to the problem of belt conveyor assembly, the pulley needs to be adjusted on the same plane.

3, we must pay attention to the quality of the triangle belt itself

Repair of counterattack:

In the sand production line, counterattack crushing is the third process. After the jaw crusher crushes large materials, it then goes to counterattack crushing. After being crushed again, it becomes the 20~60mm particles required by the customer. Counterattack is a kind of crushing machinery that uses impact energy. In order to ensure the counterattack break, it is better to continue to run in the sand production line, and to extend the life of the counterattack breaker, the user should carry out regular maintenance and maintenance on the counterattack breaker. After the new machine is put into operation, a comprehensive inspection of the counterattack must be carried out at the end of each shift. Perform a comprehensive inspection of the motor and lubrication of the counterattack broken after operation every week. The inspection content includes the tightening of the fixed parts, belt drive, bearing seal, counterattack liner, and the wear of the liner to perform a full-position inspection, and establish a regular maintenance and replacement system in conjunction with the maintenance cycle. Adjustment of the gap between the counterattack broken rotor and the counterattack liner: When the counterattack broken rotor is running, the gap between the rotor and the counterattack liner cannot be adjusted. If the material is stuck between the counterattack plate and the plate shell in blocks, it is recommended to slightly lift the counterattack frame between the readjustment of the gap, so that the block feed will become loose and the counterattack frame is easy to adjust. If the counterattack frame is not enough, you can tap on the relaxed lever (protected by a wooden board). The gap between the rotor and counterattack liner is completed by the adjustment device of the machine. First loosen the bolt sleeve, and then turn the long nut. The pull rod will move upwards, and the adjustment is good to tighten the screw sleeve. Replacement of wearing parts with counter-break: When replacing wearing parts with counter-break, first open and put it on the shelf. When in use, first remove the connecting bolts between the rear upper frame and the middle box body, and then screw it to the hexagonal head part of the flip device with a wrench, and then the upper frame is slowly opened. At the same time, the hanging device above the rack can be used to hang the rear frame. Repeat the above process, that is, close and put it on the shelf. Impact crusher's plate hammer: When the impact crusher is worn to a certain extent, it should be adjusted or replaced in time to avoid damage to fasteners and other parts. Counterattack broken liner: Open the rear cover, remove the split pins, slotted nuts, and bolts used to fix the counterattack liner, then the worn counterattack liner can be replaced.
