High-pressure roll mill comminution of heterogeneous multicomponent ...
Abstract Highly complex comminution phenomena can occur in the grinding of multi-component feeds such as ores, coal or mill feeds. High-pressure roll mill comminution of heterogeneous multicomponent feeds was simulated with artificial limestone-quartzite mixtures using a piston-die press.

Ball Mill - an overview | ScienceDirect Topics
A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages: •
