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
The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a wave-shaped design.
At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm.
Adjustment of grinding parameters:
The operation display permits convenient selection and storage of parameters such as rotation counter, rotation speed, grinding time, start and stop.
