Ore Feed Size * Work Index Hardness: Crushing & Mill Tonnage

The single most common reason for an increase or drop in the production of fines is the WORK INDEX of the ore. If you remember, the work index of the ore is a method of measuring the degree of hardness. As the ore becomes harder the fracture lines in the rock become cleaner or sharper with less crumbling of the face and edges of the mineral.
