Discussion: Raymond mill bearing wear serious problem - bearing knowledge

A, improper installation, Accounts for about 16%) 1, use brute force, when installation directly with a hammer percussion bearing to bearing damage; Is the main cause of deformation. 2, installation does not reach the designated position, install a deviation or failure to the bearing, bearing clearance is too small. Inside and outside the circle is not in uniform rotation central, resulting in different heart small ball mill. Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect. Second, the poor lubrication ( Accounts for about 50%) According to the survey, is caused by poor lubrication bearing one of the leading causes of premature failure of coal gangue crusher. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication is not accurate and so on. Advice: choose accurate lubricant or lubricating oil, the use of accurate way of lubrication filling ball mill manufacturers. Third, pollution, Accounts for about 14%) Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into the bearing inside. Main causes include: early to open the bearing packing before use, cause pollution; When installation work environment is not clean, cause pollution; Bearing of the working environment is not clean, working medium pollution counterattack crusher, etc. Suggestion: before use it is best not to unpack the bearing; Keep the installation environment clean, when installation to use the bearing in cleaning; Enhance the bearing sealing device. Four, fatigue, Accounts for about 34%) Fatigue damage is a common way of damaged bearing spiral sand washer. Common causes of fatigue damage might be: bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Suggestion: select the appropriate bearing type, timely replacement of exhausted bearing crusher price on schedule. The above is the most common kinds of cause the cause of early damage of the bearing; Cause the cause of early damage of the bearing is various, the above is a main consideration reason, sometimes may be integrated. If the bearing selection, accurate installation in place accurately, lubrication and lubricants accurate choice, bearing can be normal work time very often ceramic ball mill.
