Chat Online### Optimization of mill performance by using

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

Notes on Ball Mill DesignPower Draw. Power Draw is steady running power requirement ignoring drive-train losses and startup loads. Power Draw is reduced for regrinding ie. if 1.5 (Feed Size/Product Size) 3.0105 Feed Size 10000 microns20 Product Size 75 microns3.0 Mill Diameter 5.5 m3 Mill

Chat Online### Rod Millan overview ScienceDirect Topics

The power needed to operate a rod mill could exceed 30 of the power used in a ball mill. When they are worn rods must not stretch but break in rather small pieces so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by bar mills and this is for comparable performance.
