Nov 01 2002 · Earlier work by Fuerstenau and Kapur on the comminution of quartz in a singleparticle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22 Thus as a mechanical device for producing fine particles the ball mill is reasonably efficient energetically
The First Principle of Comminution It sometimes happens that the obvious is long disregarded and this applies to the first principle of comminution Over the years many careful laboratory investigations of comminution phenomena have been made and published Rod and ball mills from rod and ball mill work indices using procedure given in
