It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.
