Ball Milling Process

Ball Milling Process

The ball milling process can be summed up as a. It consists of stainless steel chamber and several small iron, silicon carbide, hardened steel, or tungsten carbide balls to rotate inside the mill. b. Powder of material is put in the steel chamber. The powder is reduced to nanosize using ball mill.The mill consists of a rotating shaft with four attached parallel knives and a screen occupying one fourth of the 360 degree rotation. The mill is best used to crack whole grains with a minimum of fines . It is not used as a final process for reducing the size of ingredients used in fish feeds. 2.5 Screening.
