If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind

Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent

When paired with a Hosokawa air classifier, the Alpine SO Ball Mill is capable of grinding many hard materials down to D80 = 2 µm. The Alpine SO Ball Mill has been the mill of choice for years for manufacturing high-grade mineral powders. These legacy mills are still popular due to their low operating and maintenance

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it''s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end
