Ball Mill Saturated Grinding PhenomenonMarch 14, 2017

Summary:Improve the cleanness of lubrication system in crushing and grinding equipment in beneficiation plant can ensure the smooth of lubricating oil circuit and the normal lubrication of the friction pairs

Sign Of Saturated Grinding Phenomenon

Saturated grinding phenomenon is a kind of abnormal phenomenon in the operating process of ball mill. It will reduce the grinding efficiency or even damage the ball mill. The sign of saturated grinding phenomenon: when the saturation degree is light, the sound of ball mill turn from clear to rumble and the discharge products reduce. Then the saturation degree is serious, there is no sound of ball mill, the current of main motor decrease about 30%, the discharged products reduce greatly. When the saturation degree is very serious, there will be raw materials return phenomenon in the feed opening and there are no output products in the discharge opening. When we open the observation door, we will found:

Reasons About Saturated Grinding Phenomenon

When the feeding raw materials and discharging products of ball mill lose balance, a lot of raw materials will pile up in the grinding chamber, which will lead to the saturated grinding phenomenon. Here are the reasons about saturated grinding phenomenon:

Solutions About Saturated Grinding Phenomenon

Once found out saturated grinding phenomenon in ball mill, operators should deal with it timely. Generally, operators can reduce or stop feeding raw materials to ball mill and improve ventilation in ball mill, in order to make the ball mill works with less or on raw materials and produce more heat. For the cushion adhered to the scale board or steel balls, operators should heating them till they crack and fall.
