    vertical spindle mill only tends to make the biomass a bit flatter, or break up a pellet into its constituent particles (Figures 1 and 2). Size reduction past the constituent particle size is limited and these particles need recycling through the grinding zone in the mill more than coal. The grinding of biomass therefore consumes more energy
