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%.

The product size from HPGR can be much finer than the corresponding ball or rod mill products. As an example, the results by Mörsky, Klemetti and Knuutinen [12] are given in Figure 6.8 where, for the same net input energy (4 kWh/t), the product sizes obtained from HPGR, ball and rod mills are plotted.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

Ball Charge Design Methods Ball Charge Design Methods Polysius for Finish Mills A formula that covers the entire mill as though it is a single … Mill (grinding) – Wikipedia, the free encyclopedia Ball mills normally operate with an approximate ball charge of 30%.

steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls

The ball charge and ore charge volume is a variable, subject to what is the target for that operation. The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%.
