Crushing is done in three stages, reducing to 80% passing 2 cm (3/4 inch). Rod and ball mills take the ore down to an 80% passing size of 60 microns (270 mesh). METHODOLOGY The Bond equation is a useful tool to compare predicted and actual values of energy requirements for each step in taconite comminution. Crushing and grinding energy are measured...Iron Ore Crushing and Grinding Machines.
