Size reduction is an important pre--processing of biomass using as an energy source. The end technology and final use of ground biomass depends on the biomass specie, physical and chemical properties, organic and inorganic contaminants, and geometry of the ground particles. The purpose of this study is to review size reduction equipment on basis of selection criteria, operation, productivity, performance, energy requirement, input feedstock, particle size distribution of ground biomass, and their utilization. This review and analysis shows that there is a great potential of tub grinding as a means of preparing crop and forest residues for Bioenergy purposes. The review also reveals the correlation among the grinding rate, screen size, tub speed, particle size distribution and specific energy requirement. This study shows that an amount of US$3.01/ton is necessary to process agricultural residues with a tub grinder of capacity 70 ton/hr.(Download PDF) (Export to EndNotes)
