    The energy efficiency of ball mills for use in finish grinding is relatively low consuming up to 30-42 kWh/ton clinker depending on the fineness of the cement (Cembureau 1997Marchal 1997). The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process.
