A Ball Mill grinds material by rotating a cylinder with steel or ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed.However, most Ball Mills operate at speeds between 65 and 75 percent of critical speed.
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Our Ball Mill's compact vessel with comparable amount of balls, results in a milling chamber with almost no dead-space. Less product in the ball mill during grinding leads to a reduction of waste during product changes. Making this generation of ball mills the most effective so far.
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral
