THE BOND WORK INDEX OF LIMESTONE AND ANDESITE MIXTURES
samples of pure andesite and pure limestone are separated from the ground material for experiments. The composite samples of an-desite and limestone are made from the rest, in the following ratios: limestone : andesite = 25 : 75, limestone : andesite = 50 : 50, limestone : andesite = 75 : 25. The Bond work index determination

2014年10月10日 4. Energy for size reduction • The energy dE required to effect a small change dL in the size of unit mass of material is a simple power function of the size. • Rittinger’s law: – putting p = −2, then integration gives: – Writing C = KRfc, where fc is the crushing strength of the material, then Rittinger’s law, first postulated in 1867, is obtained as: – Since the surface of ...
