Welcome to the page of the ball mill power calculators. 11 calculators are available: - Bond power formula for monochamber mill, 2 chambers mill and 3 chambers mill:
of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
A material constant which is a factor used for power calculations, expressed in N/mm 2. Machining time, T c (min) Machining length (l m) divided by the table feed (v f). Net power, P c and efficiency, η mt. Machine tool oriented values, which assist in calculating the net power to ensure that the machine can handle the cutter and operation.
Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
Aug 30, 2019· 1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting.
