To get the highest influence on energy consumption, a special type of system is used. Figure 4 gives a comparison between tube mill open circuit, closed circuit, tube mill with pregrinding unit and finish grinding system. The given [kWh/t] in relation to fineness [cm2/g] should only the level of individual systems. But values are not absolute.

There are two basic types of ball grinding systems: open circuit and closed circuit. In the open circuit system, the mill product has the fineness required for the next stage. In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next step and a thick fraction that is returned ...
