abstract:
The paper presents the results of a study on the influence of moisture content of plant biomass (sugar miscanthus, prairie cordgrass, Virginia mallow) on the parameters of compaction. In particular, the compaction ability of raw material and the quality of obtained agglomerates were determined. It was found that the higher the moisture content the greater the bulk density of raw material and the density of plant biomass in the chamber. A strong linear relationship between moisture of raw material and compaction ability was noted (R = 0.98). The lowest energy outcomes were noted during compaction of sugar miscanthus (average 22.38 J g-1) and the highest during compaction of Virginia mallow – at about 29.21 J g-1. The agglomerated Virginia mallow, with moisture of 10%, was shown to have the highest value of mechanical strength of about 0.67 MPa.
