In theball mill the disintegration of the clinker is caused by impact forces and the product is a powdery product not allowed to form a cake due to theballaction within themill in the present high pressure rollpressmethod the achievedpresscake is deagglomerated by a lowenergyimpact device such as a hammermill
The optimumballmilling speed of the ore was found to be 829 of the criticalmillspeed this work established a rational approach in the choice of grinding speed the effects of the three parameters on generation of fines were less pronounced key wordsenergy finesgrindability optimum particle size
High pressure grinding rolls hpgr are becoming an increasingly popularenergyefficient solution for comminution of hard rock ores a significant barrier to the increased adaptation of hpgrs is the current requirement for large amounts of sample for pilot testing the primary objective of the research was to develop a dembasedcomputer model for an hpgr to analyze the particle behavior in
