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. He also verified his approach with various plant data (Napier-Munn et. al., 1996). In this study, power draw of 14 multi

GROSS POWER CALCULATOR General This model uses the equations from Morrell’s 1993 PhD thesis: “The Prediction of Power Draw in Wet Tumbling Mills”. The model is also described in detail in the book “Mineral Comminution Circuits Their Operation and Optimisation” which is available from the Julius Kruttschnitt Mineral Research Centre.

19-6-2015· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. At least in terms of effective charge motion, then, there is no justification for resorting to lower mill critical speeds at larger mill

Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
