The most widely used parameter to measure ore grindability is the Bond work index (Wi). This measures the resistance of materials to breakage. The Bond standard grindability test has been described in detail by Deister (1987) and Levin (1989) who proposed method to determine the grindability of fine materials (Wills, 2006).

index (AWI). A correlation factor is applied to arrive at the index used in the grinding circuit design, when the gross autogenous index is greater than 10.0 kWh/st, because the MacPherson mill becomes less efficient as the ore becomes harder. Figure 1: MacPherson Autogenous Grindability Test

The mill reportedly rotates at 70% of critical velocity (Verret et al., 2011), or 54 rpm (Gonzalez, 2000).There is controversy surrounding the mill rotational speed. The calculation of mill critical velocity (V c) is derived from the balance of gravitational force and the centrifugal force acting on a ball, and is given by Eq., after Austin and Concha (1994) (1) V c = 42.2 (D-d) where D is the ...

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Comminution tests are commonly conducted to assess the processing behavior of ore and to aid in process design and equipment selection. Testing for Bond mill work index (BMWi), a measure of the ore grindability, and A*b, a measure of the ore crushability, is common in this regard. Get price

The resistance of ore samples to breakage (or hardness) is measured through grindability testing. Several grindability tests have been developed over the years for different applications and each test has its own strengths and weaknesses. Grindability testing is a compromise between test cost and its deliverable(s). Because a large fraction
