Investigating the controllable factors influencing the weight loss of Ball mills are the most common and versatile type of grinding mills. Mild steel or stainless steel balls are generally used as grinding media in ball mills for of ball mill, rotation speed of mill, charge weight of balls and grinding time. before and after each grinding experiment were weighted to calculate
The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
