The Ball Mill Model 11 is designed for use with 10 to 35 litre Ball Mill Jars. It is a two tier machine with each layer independantly guarded and controlled to allow flexible use. Each layer has positions for two Jars to be loaded together. The machine has a roller speed from 0-420RPM and can be adjusted by the speed controller

Development of operation strategies for variable speed

Development of operation strategies for variable speed

The results indicate that higher mill speed and lower ball load operating strategies are preferable with respect to energy savings in variable speed ball mill operations. Ore characteristic variations at the Copper Mountain Mine are significant and can cause large oscillations within mill operations

Mill Speed as a Manipulated Variable for Ball Mill

Mill Speed as a Manipulated Variable for Ball Mill

Jan 01, 1983 Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent. The manufacturer of this mill, Siemens AG, suggests that the optimization of grinding using variable mill speed could result in a 10 to 15 percent savings in energy (Meintrup, Kleiner, 1982)

Variables in Ball Mill Operation | Paul O. Abbe®

The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS
