Jan 01, 2009 Industry and Mine Automation, 2003(5): 213. (In Chinese) Fig. 3 Sizing curves of actual and simulated products 5 Conclusions 1) Experimental results show that the coal grinding process consumes less energy in vertical roller mills than in ball mills: it is very important to select the proper equipment to be used in the grinding process.
equation, the mathematical model for ball mills may be written as: F111 4) This perfect mixing model has been successfully used to simulate ball mill and rod mill operations. It can be used for steady the state and dynamic simulations of the milling processes. It is possible to evaluate Eq. (3), provided that the

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.
