ISO grindability index. The grindability of biomass for uncompressed biomass was defined in accordance with Rittinger's theory : (7) γ = ESP / 1 / xp − 1 / xf where γ is a grindability index (mm kWh Mg −1), and ESP is the specific energy for grinding (kWh Mg −1). For ISO grindability, the average feed wood chips and wood pellet size was ...

a reduction of the Bond Work Index. For most ores this reduction is in the range of 10 – 25%. This directly translates to either an increased throughput of the grinding circuit or a reduced power consumption at similar throughput rates, which will reduce the required number of mills.
