ROD AND BALL MILL POWER DRAW OBJECTIVES This module will introduce you to rod and ball mill power draw *. At the end of this module, you will be able to: • Differentiate between "energy consumed" and "power drawn" by grinding mills. • Calculate the approximate mill power draw of operating rod mills and ball mills given basic design and ...

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential ...

Mill power Usually, plant operators use mill power readings as an indior 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

19/10/2015 · Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.
