#### 92% Alumina Ceramic Grinding Ball

WEBUsually, the total charges of the alumina balls in one ball mil should be not less than 55% of the total ball mill capacity. Economical Empirical formula of charged alumina ball quantity into ball mill M= x R2 x D x L x 25%+1000 Remark M= charged alumina ball quantity (kg) D=Alumina ball density(g/cm) R=Radius of ball mill L=Ballillength
