Size Reduction and Energy Requirement - Thus, the test work index value multiplied by the product of the correction factors will provide an estimate of the true (plant) work index value. (3.42) W i = W i TEST × F 1 × F 2 × ⋯ × F 7 × F 8. Factors for condition not applicable should be taken as 1. The Bond work index value changes with the sieve size chosen during a particular

IMPACT OF PHYSICAL AND MECHANICAL PROPERTIES OF ROCKS Based on a large number of tests, Bond introduced a working index or comminution parameter that represents the resistance of the material to crushing and grinding. Characterization of rocks for selection of crusher can be done in different ways, and the most commonly used is Bond work index (Tavares and Carvalho 2007). Holmes (1957) proposed a modification of Bond's equation with the

This knowledge is essential to define the required ball mill layout and production capacity. In order to perform the Bond Index Test successfully it is necessary to use pre-crushed sample material as defined below: Module Ball Mill. Minerals pre-crushed to < 3.35 mm and sieved Bond Work Index - an overview | ScienceDirect 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
