Industrial Ball Mills Steel Ball Mills and Lined Ball Ball Mills Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800 s The basic construction of a ball mill is a cylindrical container with journals at its axis
High Pressure Grinding Rolls HPGR have been used for over 20 years however the technology has not received wide industry acceptance despite reports of substantial energy advantages One barrier is that full and fair consideration cannot be given to HPGRbased comminution circuits for earlystage mining projects because industry standard tests require large sample sizes for evaluation of
