| Summary: | The definition of the physical and mechanical properties of
sugarcane trash pellets were necessary for the design considerations relating to storage, handling and
processing 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 determine
their effects on bulk density, true density, porosity, durability and
compressive strength. The results show that the mixing ratio by weight of 1.0:0.25:0.85 and pelleting speed of 120
to 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. |
