Mill Capacity Calculations
Mill Capacity Calculations. There are a large number of formulae for the calculation of the capacity of a milling tandem. Hugot gives the following formula: A = 0.9 c·n·√N·(1-0.06·n·D)·L·D 2 /f. ... which means mathematically that the mill capacity will increase with speed, reach a maximum and then deacrease, as the speed increases. ...
