Jun 19, 2015· The effect of Ball Mill RPM speed going from subcritical to supercritical helps understand the Ball Mill Working Principles of ballonball VS ballonshell grinding. The Motion of the Ball .
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ''chunk size'', product size as P80 and maximum and finally the type of circuit open/closed ...
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.
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, semiautogenous and ball mills which is based on the motion of grinding charge inside the mill.
mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than due to an extra amount of nes present being fi fi ner than 650 μm. These fi nes proceed to the ball mill improving the ball mill effi ciency. Also, the plotted rod mill P80 value, as shown in Figure 1, is 2900 ...
