When you use dolomite high pressure grinding mill, it maybe appears various failures because of improper use and other reasons. If you do not solve it as soon as possible, it will greatly affect production efficiency. In order to solve common problems, we sum up three points to analyze symptoms and causes of malfunction.

First, failure: the current of dolomite high pressure grinding mill it is too strong, and the rollers of hanging shaft member often can not rotate.
Reason: hanging shaft member. After the disintegration, you will find that suspended sliding bearing shaft does not rotate, and there is a lot of sludge in the intracavity of overhang shaft. The reason is that the air gap is too large, and the pressure in intracavity is smaller than dolomite high pressure grinding mill’s. It makes dust into the cavity.

Second, failure: abnormal sound in the grinding room of dolomite high pressure grinding mill. Rollers on grinding ring make knocking noise.
Reason: milling chamber of dolomite high pressure grinding mill. After stopping the machine, opening the milling chamber, and manually opening the disc drive, you will find some roller do not turn sometimes, roller and grinding ring has collapse blocks. After analysis, it is caused by poor lubrication of roller bearings.

Third, fault: abnormal wear and tear occurs on the roller and grinding ring of dolomite high pressure grinding mill. Roller surface are changed into a concave surface, sometimes uneven streaks appear, and grinding ring becomes concave.
Reason: air hose is worn out, The main reason is constant scour of the powder in the mill chamber of dolomite high pressure grinding mill.
