摘      要：The change in physical properties of wood pellets,with a focus on particle size distributions due to pellet breakage and attrition,was studied in a large-scale(∼450 ton/h)transportation *** locations with a high probability of breakage through the whole transportation system were chosen and sampled to study the effect of transportation system design and operation on the mechanical properties of *** density,mechanical durability,moisture content,and particle size distribution of pellets were characterized for each *** of variance showed that there were significant differences between the percentages of small particles(5.6 mm)in the samples taken at different locations,especially at one with a vertical free fall of 7.8 *** average,this relatively long drop increased the proportion of particles5.6 mm in the samples from 8.73%to 14.09%,and that of particles3.15 mm from 4.82%to 9.01%.Moreover,the measurements showed a wide deviation in the mechanical durability values,between a minimum of 90.8%and a maximum of 98.7%,which were not correlated to the sampling points but related to pellet *** can be concluded that pellet transportation systems require more dedicated design strategies to prevent breakage and attrition.
