Ball Mills The final stage in comminution are performed in ball mill. Balls have a greater surface area per unit weight than rods better for fine grinding. Length to diameter ratio (L/D) is 1.5 to 1 and less. If L/D is 3-5, called tube mill or pebble mill. The grinding mediums are pebble or flints. It is widely used in ceramic raw material.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5] Autogenous mill
