Abstract. Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation of the grinding process in vertical roller mills was carried out. The simulation calculation used a breakage function, B. The results indicate that the breakage function, B, and ...

In addition to the information given, it is possible to surface grind on a vertical mill. There are quite a few small mills which are pretty rough on facing and, of course, there is quite a lot of inaccuracy generated by flycutting. Believe me, the old English model engineering press was full of it at one time.
