Lightweighting is a design strategy to reduce energy consumption through the reduction of mass of a product. Lightweighting can be applied to machine tools to reduce the amount of energy consumed during the use phase. Thus, the energy cost of machine operation will be reduced. One might also hypothesize that since a lighter-weight machine tool requires less material to build, …

The crushing action of a 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.
