Ron Davis, Manager, Training and Development, WIDIA Products Group. In milling, cutting forces are exerted in three planes to deform and shear away material in the form of a chip. Tangential cutting forces overcome the resistance to rotation and account for 70 perent of the total force. Feed forces account for 20 percent of the total force.

How to Make a Ball Mill: 12 Steps (with Pictures)
Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry
