The reduction ratios for each successive crushing and grinding process influence the distribution of particle sizes and the energy use in the process. Energy use is relatively low when particle sizes are consistent. Finer particles resist breaking and are displaced, causing energy to dissipate. Larger particles reduce grinding efficiency.Getting intense about grinding - CIM
