Why is ball milling used in powder metallurgy?
Ball Milling: Ball milling is an old and relatively simple method for grinding large lumps of materials into smaller pieces and powder form. Principle of the process: The principle is simple and is based on the impact and shear forces. Hard balls are used for mechanical comminution of brittle materials and producing powders.See all results for this questionWhich is the best description of the milling process?Milling: The basic principal of milling process is the application of impact and shear forces between two materials, a hard and a soft, causing soft material to be ground into fine particles. Milling techniques are suitable for brittle materials. Two types of milling are; i) Ball Milling ii) Attrition Milling. 16.See all results for this questionWhat are the factors that affect the productivity of a mill?The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.See all results for this question
