What are the common faults of horizontal ball mill grinding machine?

1. The material has high moisture content, the ball sticks to the mill, and the grate is blocked:
Reduce the filling material, reduce the particle size of the mill; reduce the moisture content of the material, and clean the grate.
2. The reducer bearing is hot and the running sound is abnormal:
Temperature detection of the reducer bearing, dredge the exhaust hole; the balance wheel and the intermediate wheel are installed according to the specified meshing teeth.
3. The main bearing temperature is too high, hot, smoking or melting:
Oil supply interruption or insufficient oil; poor oil quality or sand and debris entering the bearing; the main bearing is not installed straight or level; the cylinder drive shaft is bent; the oil groove is too deep and the pad and the shaft contact so that the oil cannot enter the pad; the oil supply device fails, the oil supply is interrupted or insufficient; the bearing clearance does not meet the requirements and the contact with the shaft is poor; the lubricating oil viscosity is unqualified; the coupling is not installed correctly; the main bearing cooling water is insufficient or the cooling water temperature is high. The solutions include cooling down the temperature, then stopping the grinding for inspection and adjustment, increasing the oil volume; cleaning, replacing new oil; adjusting the level; adjusting the alignment; inspecting, repairing, and adjusting; repairing the oil supply device; adjusting the clearance, scraping the bearing shell or repairing the journal; replacing the lubricating oil with appropriate viscosity; adjusting the alignment; increasing the water supply or reducing the water supply temperature.
4. Partial wear of the cylinder:
The liner is not installed in a misaligned manner; the liner continues to operate after it falls off; there is material flushing between the liner and the cylinder. The solutions include staggered installation of the liner; repairing or replacing the liner.
5. The gear bearing vibrates, the noise is too loud, and there is a knocking sound:
The bearing cover or bearing seat bolts are loose; the bearing is too worn; the bearing is poorly installed; the gear is too worn and the lubricant is too dirty; the large gear or the matching bolt connection is loose; the gear meshing clearance is too large or too small; the gear processing accuracy is not high. The solutions include tightening the bolts; replacing the bearing; repairing or replacing the gear, strengthening the lubrication; tightening the bolts or replacing the rubber ring.
6. The ball mill cannot start, the motor is overloaded:
There is a problem with the motor system; there are obstacles in the rotating part; the machine is shut down for a long time, the materials and grinding bodies in the ball mill are not cleared in time, the wet materials condense into blocks, and the grinding bodies are not thrown off when the machine starts, which increases the load on the motor. The solutions include checking and repairing the motor system; clearing obstacles in the rotating part; cleaning the materials and grinding bodies in the ball mill, cleaning out the agglomerated materials and part of the grinding bodies, and stirring and mixing the remaining materials and grinding bodies.
7. The gear tooth surface wears too fast:
Poor lubrication or the lubricating oil is mixed with impurities, metal, etc.; the meshing clearance is too large or too small, and the contact is poor; the gear processing quality does not meet the requirements; the material is poor, the tooth surface hardness is not enough; the assembly is poor; the ore sand and other abrasive particles enter the teeth. The solutions include strengthening lubrication or replacing the lubricating oil; adjusting the meshing clearance; strictly controlling the processing process and eliminating unqualified parts; tempering treatment; readjustment.
