【 摘 要 】

The definition of the physical and mechanical properties ofsugarcane trash pellets were necessary for the design considerations relating to storage, handling andprocessing equipment. The mixing ratios of ground sugarcane trash:cassava starch:water content (1.0:0.25:0.85 and 1.0:0.25:1.40 by weight) and pelleting speeds (100, 120, 140, and 160 rpm) were considered to determinetheir effects on bulk density, true density, porosity, durability andcompressive strength. The results show that the mixing ratio by weight of 1.0:0.25:0.85 and pelleting speed of 120to 140 rpm were optimum for producing the sugarcane trash pellets. At the  moisture content  of 12.01% (wb), the bulk density, true density,durability and compressive strength of biomass pellets were  in the range of  330.93 to 365.00 kg/m3,  860.38 to 918.43 kg/m3, 99.34 to 99.46 % and 5.15 to 6.43 MPa, respectively.
