Dec 01, 2009 1.. IntroductionConventionally multi-compartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls (HPGR), vertical mills and Horomill ® in cement plants. As recorded in the literature, Horomills ...
