In the production line of ultrafine grinding mill, it will have some faults and it needs clients to have the regular maintenance. Here will introduce the three common main faults and provide the related solutions: regular check the gear pair, bearing working conditions; regular check grinding roller wear situations and clean the foreign matters; do the gear pair lubrication works.

1. Regular Check the Gear Pair

In the working process of the ultrafine grinding mill, if the client finds there is abnormal noise and the machine works unsteadily, the bearing temperature will rise and show abnormal phenomena. The problem needs to be checked in time and appropriate solutions provided.

When the clearance between the small gear and large gear becomes larger, the client should stop the machine and adjust the center distance between the gears to ensure the machine operates normally. When the small gear works through the rotating direction and the gear side has seriously been worn, it needs to stop and check and change the working side. It will let the other side being the main driving side. When a gear is broken, it needs to be replaced with a new one.

When the bearing space is becoming large, it needs to maintain the small gear shaft. When the clearance of the small shaft becomes too large, copper sheets should be installed to reduce the clearance. When the space cannot adjust, or it works rigidly, it needs to change the new one.

2. Regular Check the Grinding Roller

the successful working of ultrafine grinding mill is for the grinding roller rotating. Under the function of grinding roller, it will do the rotating movement and this can make the materials which are between grinding roller and grinding ring grinded. When there are hard materials inside the machine that cannot be ground, the machine will not run smoothly. The clients need to check the machine immediately and clean the matters.

3. Do the Gear Pair Lubrication Works

for ultrafine grinding mill, the following parts need to be lubricating: bearings, various gears and so on. Currently, the level of automatic lubrication has been greatly improved, which reduces the manual workload. For clients, you need to lubricate the machine timely.
