The working principle of ball mill
Mainly the rotation speed of the ball mill, the size and number of the grinding body, the volume of the object to be polished, the grinding medium and the grinding time. 1. the speed of the ball mill When the ball mill rotates, the ball movement in the barrel may have three states (pic 8-1).

Ball Mill Critical Speed
Low-speed units include ball or tube or drum mills, which normally rotate at about 15–25 rpm. Other types of mills, e.g., ball-and-race and roll-and-race mills, that generally fall into the medium-speed category may also be included in this category provided their speed is less than 75 rpm.

Ball Mill Critical Speed
The critical speed of a rotating mill is the RPM at which a grinding medium will begin to “centrifuge”, namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed.

The mill productivity also depends on many other factors, including the physical-chemical properties of the feed material, the filling of the mill by balls and their sizes, the armor surface shape, the speed of rotation, the milling fineness, and the timely moving off of the ground product.
