Ball 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%.
Design Method of Ball Mill by Discrete Element Method collected. The diameter of the gibbsite powder was measured using a Master Sizer 2000 (Sysmex Corpora-tion). Details of the experimental conditions are given in Table 2. Results and Discussion 1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis-
To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill .
