The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour.

First, the weight loss of the ball leads to a decrease in its kinetic energy and a consequent reduction in energy transfer or milling efficiency. Second, the degree of filling of the mill is raised so the balls mobility becomes more difficult and as a result the kinetic energy of the balls are reduced.

To find the power at the mill pinion, multiply an E value by the circuit solids feed rate (feed rate of dry solids to primary mill or the dry solids flow rate of product in the cyclone overflow). Power as kW = E * (t/h dry solids) A ball mill can safely operate at 90% of its motor rated power, so choose a motor size like this:

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. The % loading or ...

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...
