Main unit is the most important parts of ultra fine grinding machine, which is professionally producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, the moisture under 5% such as calcite, chalk, limestone, dolotomite, kaolin, bentonite, talc, mica, magnesite, illilte, pyrophyllite and ermiculite, sepiolite, attapulgite, rectoreite, diatomite, barite, gypsum, alumite, graphite, fluorite, rock phosphate, Kalium ore pumice, etc., totally more than 200 kinds of mateirals. There are five comman problems exiting in main unit. We will explain how these problems is caused and how to solve them.
| Common Problem |
Reason |
Solution |
| The temperature of bearing is too high |
1.Overloaded 2. Main unit, classifier bearings are note well lubricated 3.The deflection of rollers, vibration, and abnormal sound occurred 4. Bearing installation error |
1. Reduce feeding amount, keep the input and output be balanced against each other 2. Fill oil timely 3. Open the machine to check if rollers and shafts are seriously worn out; replace spare parts according to the situation 4. Re-install main unit, adjust the bearing gap to ensure proper bearing load |
| Processing materials fall out |
1.Overfeeding; 2.Input and output quantities are not balcanced |
1.Stop feeding, until the current resume to normal. then start vibrating feeder again 2. Adjust feeding and classifier, stabilize the current of the blower, balance input and output of processing materials. |
