Common faults of industrial mill: mill electrical flow is large, hanging shaft parts often rollers do not move, the current is too high; The grinding cavity sound is abnormal, and the roller has a crash sound on the grinding ring. Lubrication pump feed oil is not smooth; Transmission large belt wheel oil leakage is serious; Abnormal wear of rollers and grinding rings. Roller surface is easy to grind into concave surface, sometimes found that there are uneven stripes, grinding ring also appears concave grinding surface; The air duct connecting the roller assembly is worn out. 

Analysis of common fault causes of industrial mill

There are often some faults in the process of use. The reasons for the faults are analyzed as follows: 

1. The whole unit has more than 10 motors of different sizes, therefore, the fault of the motor can not be ignored. High temperature is one of the main causes of motor damage. Causes of high temperature include bearing oil shortage, bearing into dirt, bearing damage or; Motor overload, etc.

2. Cleaning screen fault cleaning screen vibration or screen frame shaking. The cause was loose bolts or wedges. There are grains of wheat in the sand. The reason is that the inner damper of the stone mouth is small, or the Angle of the screen surface is not appropriate. The wheat was crushed too much. The reason is that the gap between the teeth plate and the screen is too small, the screen hole is too large or damaged. 

3. The screw stirrer fails to discharge grain at the outlet. The reasons are motor steering is wrong, the discharge port is blocked, the agitator blade is broken and so on. The mixer shaft does not turn. The reason is too much feed, drive belt skid, etc. 

4. If the fuselage of the mill is shaking, the bolt connecting the grinding head and the frame should be tightened. Production is down. The spring should be tightened to ensure that the gap between the two ends of the roller is consistent, and the worn teeth should be repaired. Flour has a high temperature. Should be adjusted to loosen the grinding roller, such as grinding roller wear should be repaired or replaced; When the machine temperature is high in summer, it should be stopped for heat dissipation. No bran comes out. 

Common reasons are spindle steering is wrong, screen frame seal is not strict or screen mesh damage. No powder or less powder. The common cause is blockage of the screen.
