Description

A detailed overview and knowledge of the characteristics of a raw material is of utmost importance, especially when planning the layout of a crushing plant. In order to minimize all possible risks extensive trials are necessary to obtain information on the properties of the raw materials. A clear definition of the required crushing capacities and the desired product quality can be precisely determined by using the Bond Index test methods. Using the Bond Index test procedures it is possible to calculate crushing / abrasion behavior of mineral samples. 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 Drillcore pre-crushed to < 3.35 mm and sieved Half Drillcore pre-crushed to < 3.35 mm and sieved The Bond Index conforming ball charge consists of: 43 x 1.45” balls 67 x 1.17” balls 10 x 1” balls 71 x 0.75” balls 94 x 0.61” balls The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of 20.125 grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well-rounded corners. Module Rod Mill Minerals pre-crushed to < 12.50 mm and sieved Drillcore pre-crushed to < 12.50 mm and sieved Half a drillcore pre-crushed to < 12.50 mm and sieved The Bond Index conforming rod charge consists of: 6 rods of 1.25“ diameter and 21“ length 2 rods of 1.75“ diameter and 21“ length
