The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

2006). The laboratory bench-scale SAG mill reproduces operating conditions of a commercial SAG mill, in a closed circuit dry grinding environment. The ground product for the laboratory SAG mill is then submitted to the Bond ball mill work index test. The number of SAG mill …

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.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

If a ball mill contained only coarse particles, then of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.

An example would be a closed-circuit ball-mill feed calculation cell that contains the value 100 on the first iteration, 0 on the second, then back to 100 again repeating the cycle. Backward-Chaining Spreadsheet programs that calculate by means of backward-chaining determine the order of calculation by examining relationships between cells.
