— According to statistics the energy consumption of grinding is about 10 times that of crushing [Morrell 2004 2008 and 2009] Given the energy consumption distribution of ore crushing and grinding [Morrell 2004 2008 and 2009] the particle size of the crushed final product should be reduced as much as possible in the production process
