Ore Hardness Testing -SAG Mill Tonnage Estimation Method
For design purposes, you need an estimation or prediction of your SAG Mill’s tonnage; well, there are 3 ways to generate good rock “ore” hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three “religions” of grinding, and there are small-scale tests suitable for all three of the major religions ...
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.
