Bond index and energy index? - Page 1 of 2

Sep 08, 2013· The difference between the Energy Index and the Bond Work Index is that the Bond index is intended for use with actual mills whereas the Energy Index is directly obtained from the results of laboratory mills. However, the Energy Index is directly related to the Bond Work Index by the formula;-Work Index = C * Energy Index (where C is a constant)

Breakthrough in Clinker Grinding

Once the Bond Work Index is known for a specific material the equation can be used to calculate the energy requirements for various ranges of input and output sizes. Bond's work index is given below: The indices derived by Kick, Bond and Von Rittinger all assume a constant energy requirement per unit of

THE BOND WORK INDEX OF LIMESTONE AND ANDESITE …

The Bond work index determination according to the standard Bond's test is done on all these samples with compara-tive sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): (√ √) (1) where: W i – Bond work index (kWh/t); P c – test sieve mesh size (µm);
