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 ...

A rolling mill is a mill that uses compression on a single, double or even triple cylindrical wheel that is rotated along the long axis against another wheel or a plate. The cylindrical wheels are mounted horizontally and only one is run by a motor to move the grains between the two wheels while the other moves slowly as a result of friction.
