The Energy Efficiency Of Ball Milling In Comminution
The Energy Efficiency Of Ball Milling In Comminution

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.
