The absorbed power is calculated by multiplying the torque on the driving shaft with the shaft speed (rad/sec) and hence excludes any losses associated with the gearbox and motor. The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test ...
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).
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.

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.

80 sizes typically reached by conventional ball milling. The delineating size between coarse and fine grinding is 750 µm. SMC test results are used to determine the Drop Weight Index (DWi) and the coarse ore grinding index (M ia). Test data from the Bond ball mill work index test is used to calculate the fine grinding index (M ib). The M ia and M
M/s Holderbank Engineering, Canada has developed a control strategy for ball mills which can maintain a mill production near optimum, with little operator intervention. The main principle of the concept is that maximum production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific

balls which exist in mill, 𝐴𝑏: each ball abrasion (g), 𝐴t: total ball abrasion in the mill (g), 𝑣b: each ball volume (m3), 𝑓b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for 𝑓b = 2%, total ball abrasion will get 60.96, finally.
mill test, the calculation method of the mill energy specific cumulative grinding rates is shown by the following example. Using plant data, the value of E is the specific energy input to the solid material as it passes through the plant mill (the mill power draw divided by the mill .
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
