Abrasion and Strength of the Biomass Pellets as Main Mechanical Stability Characteristic

S. Narra, C. Glaser & P. Ay
Biomass densification through a pelleting machine conveys benefits such as reduced dust emissions and reduced transportation­ and storage costs. Pellets produced with low mechanical strength characteristics result in fragmentation and abrasion leading to a low efficiency product. The efficiency of the pelletisation process can be determined with the help of the parameters durability (abrasion) and strength (diametrical compression tests). The durability and the strength parameters give the most important physical quality of pellets. The pellets...
