Effect of ball mill grinding parameters of hydrated lime fine grinding .The influence of several grinding parameters such as charged material volume, ball filling ratio, and mill rotation speed on energy efficiency of fine grinding of hydrated lime and the product fineness of hydrated lime was studied experimentally using a laboratory scale ball mill. The product size and surface area of the.grinding area in a ball mill,A discussion on the measurement of grinding media wear .A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi-autogenous grinding, and . Wear accelerated by corrosion depends on two factors: firstly, the area on the metal that depassivates at each abrasion event, and secondly, the amount of metal.
