THE BOND WORK INDEX OF LIMESTONE AND ANDESITE

THE BOND WORK INDEX OF LIMESTONE AND ANDESITE MIXTURES** Abstract This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball value is found in a laboratory Bond ball mill by simulating dry grinding in a closed circuit until the 250% circulating load has been achieved (Magdalinovic, 2003).

Investigation into the applicability of Bond Work Index (BWI)

Oct 15, 2015The Bond Work Index ( Wi) expresses the resistance of the material to grinding to a specified product size, and the higher the value of Wi, the more difficult the material is to grind to the required product size. The Work Input W, gives the power required by the mill to grind the product to the required product size.

two. Results of Bond ball mill tests conducted with closing screens of 75 m or finer are to be treated with caution. The Bond Work Index relationship has been noted to apply down to approximately 70 m, and perhaps no finer, without making qualifications. Calculations: First, calculate the actual Operating Work Index, WloACT-, of the

BOND'S WORK INDEX: WHAT IT IS AND WHAT IT ISN'T

The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of –0.45 in the 100 m to 200 m size range, not the –0.50 exponent empirically measured by F. Bond. The work index increase between 100 m and 76 m is due to a porphyritic grain size that causes a spike in energy
