THE BOND WORK INDEX OF LIMESTONE AND ANDESITE MIXTURES** Abstract This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball The energy required for crushing and grinding is presented by the Bond work index and is determined by means of Bond grindability test.

## Universal Hardgrove mill, Bond index, grindability, specific grinding work, closed- cycle grinding. 1. and Bond grindability tests with limestone, marble and.

Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face4A results less than 20kwh/t, remaining 6 samples are marked as hard - rock because of high energy consumption and low grindability rate. Ball Mill Bond Work Index for Limestone – Ore Beneficiation Plant. The Bond Work Index indicates a relative grindability of the limestone. The Work Index number is developed by grinding a small sample of the material in a …. »More detailed. The Bond work index of limestone and andesite mixtures It is also concluded that the Bond work index of the mixtures is often higher than the weighed-average value of the individual components There are two important factors in rock fragmentation: (1) total energy consumed and (2) size distribution of fragments. In a study on crushing and grinding, fracture toughness has been taken as a key index similar to the Bond Work Index. Due to many cracks dealt with, rock fragmentation is a very complicated and difficult fracture problem. Limestone is a commonly occurring sedimentary rock, predominantly composed of calcium and magnesium carbonate (MgCO 3) with various amounts of silicates, metal oxides, and other impurities. Mineralogically, limestone may be regarded as calcite, magnesian calcite, dolomite, The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Composite samples of andesite and limestone were prepared in ratios: limestone : andesite = 25 : 75, limestone : andesite = 50 : 50, limestone : andesite = 75 : 25. The Bond work index determination according to the standard Bond test was done on all samples with a comparative sieve size of 74 micrometers.
