to get smaller by either breakage, attrition of fines or by giving away mass. Pellets smaller than 1.5 mm agglomerate and receive mass upon collision with larger pellets. Conclusion: A new mechanism of [...] undergo breakage, other pellets continue to deform plastically into a dumbbell shape, as shown in figure 1. Fine fraction is attached to the dumbbells. Upon collision of two pellets, the pellets exchange mass [...] This size alignment is encouraged by agglomeration of pellets which size are short of approximately 1.5 mm. Finally, pellets with a monomodal size distribution are received. …
