After reach and study, when ball mill has the problems such as overheat of worm wheel and worm gear, bearing damage, excessive abrasion, we need to replace and repair ball mill in time. We need to change the bearing of ball mill, remove the impurity inside ball mill and change lubricating oil, change worm wheel and worm gear of ball mill. When the driving device of ball mill goes loose, or worm wheel wears out or bearing of ball mill wears out or screws become loose, we can cool ball mill trough fixing the driving device of ball mill, changing worm wheel of ball mill, changing bearing, tighten screws of ball mill, remove impurity. When ball mill goes overloaded, lubricant oil is too much or too little, we should adjust ball mill to the appropriate load or choose ball mill of larger size and add lubricant oil in driving device of ball mill. When the output shaft and the driving device of ball mil join badly, we should adjust the output shaft of ball mill to suitable position to fit the driving device of ball mil, so as to eliminate the noise of ball mill. Besides the above-mentioned approaches, we can also get solutions to cool ball mill.Scientific management, advanced processing technology and innovative manufacturing theory make Hongixng become the exporting base of ore separating line, wet magnetic separator and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market.The ball mill is simplified by level, feeding hollow shaft and the grinding head and other components, simplified is a long cylinder, cylinder is filled with the grinding body, cylinder body is a steel plate, a steel plate and simplified fixed, grinding body is usually steel ball, and different diameter and certain proportion into the barrel, the grinding the body can also be used steel, it can according to the grinding particle size is selected, the material from the ball mill feed end of hollow shaft into the...
