Development of size reduction equations for calculating

Size reduction is an unavoidable operation for preparing biomass for biofuels and bioproduct conversion. Yet there is considerable uncertainty in power input requirement and the uniformity of ground biomass. Considerable gains are possible if the required power input for a size reduction ratio is estimated accurately. In this research three well-known mechanistic equations attributed to
