In particular they classify the ball mills in two groups depending on their operation mode: direct and indirect milling. In the rst case rollers or mechanical sha s directly act on the particles and transfer the kinetic energy. In the second case the kinetic energy is rstly transferred to the mill body and then to the grinding medium.
