Circulating Load Calculation Formula
Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

While, not knowing if this is the feed or discharge end trunnion, there ...
How safe is it to ball mill
As far as ball mill safety goes, the motor should be completely separated from the milling area, so that no powder can get to the motor. I also barricade my ball mill with a thick inner layer of Styro surrounded by an outer layer of concrete blocks. The least you can do is prepare for a potential accident.

How a Grate Discharge Ball Mill Works
Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...
