QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE
2016. 12. 27. 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

A meaningful expression between bond work index,
2005. 8. 1. The high work index of limestone could be due to its strong interlocking matrix and micro-crystalline structure, whereas marble has larger crystals. The friability value ( S 7 ), Bond work index ( W i ) and grindability index ( G ) are compared with each other and the

MINE 331 Bond Work Index ii MINE 331 Bond Work
Limestone is theorized to have a Bond Work index with a value of around 11. This is due to the main presence of calcite, a softer mineral. Sandstone is also often referenced with a

18th Relationships Between Bond's Grindability (G ) and Breakage
2009. 9. 17. Bond grindability value s of limestone sample were appeared 6.14 g/rev, 2.89 g/rev, 2.58 g/rev, 2.48 g/rev, 2.42 g/rev and 1.54 g/rev, respectively. Then, the standard sets of grinding conditions used are shown in Table 2, for a laboratory mill of 6283 cm 452 .

Bond Work Index an overview ScienceDirect Topics
The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger’s law. Accordingly, the energy consumed in reducing the particle size from x F to

CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL
2014. 6. 27. The value of Bond work index of the above samples has shown a variation from 10.8 kwh ton-1 for bauxite (high abrasion value and low compressive strength) to 20.4 kwh ton- 1 for granite (low abrasion value and high modulus of elasticity). The correlation between the abrasion value(X2) and work index (Wi) is found
