Get PriceBall mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Get PricePlanetary Ball Mills are used wherever the highest degree of fineness is required.In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and ...
