plot will still be created. The mill speed did not have an effect on grinding energy efficiency and it was found to be a reliable indicator of net mill power draw between 1400 and 2000 RPM, as shown in Figure 1. Less residence time was required to grind to a given target size as the mill speed was increased.
The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.
Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600 Calculated ballmill power draw from the m odel derived, kW Data compared Line y=x Fig. 2. Comparison of the ball mill power draw from the Denver slide rule and the proposed model. Dashed line corresponds to y=x.
CALCULATION OF BALL MILL GRINDING EFFICIENCY calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply
