Common Faults And Solutions Of Ball Mill

As one of the commonly used milling equipment, the common faults and solutions of ball mills are as follows:

After The Motor With Reducer Starts, Vibration Occurs

Cause Of Issue:

• The gap between the two wheels of the coupling is too small, it is difficult to compensate for the amount of movement caused by the magnetic center of the motor when it is started;
• The transmission coupling of the reducer, the motor and the transmission shaft does not maintain a high degree of coaxiality, resulting in the two shafts not being concentric;
• The connecting bolts of the coupling are not tightened symmetrically, and the tightening force is different;
• The outer ring of the bearing is not fixed well.

Solution:

• Adjust the wheel clearance as required;
• Make the two axes concentric;
• Tighten the coupling bolts of the coupling symmetrically with the same torque;
• Fix the bearing outer ring.

Lubrication System Oil Pressure Is Too High Or Too Low

Cause Of Issue:

• The oil pipe is blocked or leaking;
• Insufficient fuel supply;
• There is a problem with the oil pump.

Solution:

• Check whether the oil pipe is blocked or leaking oil, and timely repair or replace the oil pipe;
• Replenish fuel supply regularly;
• Check whether the oil pump enters the air or oil leakage, and deal with it in time.

Overheated Bearings, Overloaded Motor

Cause Of Issue:

• The lubricating oil grade is inconsistent with the equipment manual, or the lubricating oil is deteriorated;
• Too much or too little grease;
• The lubricating pipeline is blocked, so that the lubricating oil does not enter the lubricating point;
• The bearing or coupling is not installed correctly;
• The gap between the journal and the bush is too large or too small, and the contact is poor;
• The oil groove is damaged and oil cannot flow into the journal or bush.

Solution:

• Use the correct grade of lubricating oil and replace the deteriorated lubricating oil;
• Add enough oil according to the regulations, generally 1/3 to 1/2 of the bearing gap is more appropriate;
• Dredge the lubrication pipeline;
• Install bearings or couplings correctly;
• Adjust the gap between the journal and the bush;
• Check the oil tank in time.
