Analysis Of Power Draw In Ball Mills By The Discrete

Analysis of Power Draw in Ball Mills by the Discrete Element Method. Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge.

May 28, 2018 There are many different types of mills ball mills, rod mills, SAG Semi-Autogenous Grinding and autogenous mills. In a ball mill, steel or stone balls are mixed with the ore and during rotation of the drum the ore is ground, by friction and compression, into a suitable fineness for the next step in the process. The main component of all ...

Ball Mills An Overview Sciencedirect Topics Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
