Circulating Load Calculation Formula

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 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour.

Mill Steel Charge Volume Calculation

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.

Material Hardness - from Types of Hardness to Testing & Units

Even ceramic and composite material hardness measurements are possible. The most commonly used scales are "B" and "C". In Rockwell hardness test, prior to applying the testing load, a small minor load is applied to seat the indenter into the test piece and remove the effect of any surface irregularities. This provides better accuracy.
