Ore Hardness Testing -SAG Mill Tonnage Estimation Method

Last, in the ore hardness measurement world is the “Australian” religion that takes the form of either the JK drop weight testing and population balance models by JK SimMet, or the SMC test and its power-based models by Morrell. The power-based SMC test is comparable to the other power-based methods ($1200-1500 per sample) but, arguably, has the poorest calibration to heterogeneous

Hardness Comparison Chart Hapco, Inc.

Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s. A chart showing general hardness comparisons is below. Some of HAPCO’s materials are available in both Shore A and Shore D.

Vickers hardness test Wikipedia

The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness.
