How to achieve the "downsizing" of Ball mill ? How to reduce or even eliminate swelling phenomenon is a question that the industry need to think about. When the ball mill swells, the material and the milling balls will accumulate and fill the cylinder. The rotating speed of cylinder will become slow. The motor is in overload state, which will cause significant loss of life of the ball mill motor, Or even directly make the motor scrap. Here, Henan Zhengzhou Mining Machinery Co., Ltd. is committed to the study of the ball mill failure for several years, and eventually gets the solution of swelling situation of ball mill:
1. See if there is the phenomenon that material can’t go into the feed end of the energy-saving ball mill ;
2.  Listen to the voice of the process of Energy ball mill operation. If the sound is small and muffled, it shows that there is too much material in the ball mill.
3. Observe the electric current changes of ball mill current control cabinet. If  it becomes smaller, cut off the operation of the ball mill right way to check that if there appears swelling phenomenon.
