8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill

Ball mill is a hollow cylinder which rotates about its axis. The axis can be horizontal or be at some angle to the horizontal. The shell of ball mill can be made of strong steel and coated with refractory materials. Ball mill is partially filled with free moving media balls which can be made of steel, stainless steel, ceramic or rubber.

The ball mill is a device for coarse, fine and ultra-fine size reduction or homogenization of ground material. It consists of a rotating grinding chamber in which the ground material is crushed by grinding media. The ball mills described here, in which balls are used to crush the ground material, are to be distinguished from stone mills.
mill grinding rate over the materials grindability as measured in the lab. Mill percent solids optimization has thusly been achieved McIvor et al., 2000. For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.

Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include Speed of mill rotation Mill diameter Mineral density
Oct 20, 2016 The original charge to a mill is generally between 40 and 50 of mill volume for ball mills and 35 to 45 mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20 to 22 for new rods.
