8 Common Bearing Problems & How You Can Prevent Them

You can usually identify this problem by looking at the bearing and seeing discoloration on the ball and raceway. It can also appear as an overloading failure because the heat causes the bearing ring to expand, increasing the resultant load to the bearing. 2. Your Bearing is Rotating Faster Than the Grease Rating.

Ball Mill Loading - Wet Milling - Paul O. Abbe

Add to this another 45% to 50% above the ball charge for total of 58% to 63% product loading. This level of liquid loading should leave some air space above the liquid to allow for expansion of the liquid as it heats up during the milling process. So as a rule of thumb we use a maximum of 60% liquid loading. See our Size Reduction Options
