Oct 22, 2016 Based on the energy balance calculation of heterogeneous grinding, energy split factors (ESFs) of components in the ball-and-race mill at different grinding time are firstly computed. These two energies are calculated by the modified model with parameters in the mixture and single breakage, respectively.
Jun 01, 2018 Energy-size reduction experiments of particles in narrow and wide size were conducted in a modified ball-and-race mill, namely Hardgrove mill, with the addition of a power meter. Materials were SCC particles in size of 2.82 mm, 21.25 mm and 1.250.71 mm. SCC particles in neighboring size were mixed with mass ratios (coarse-to-fine) of 31, 11 and 13.
