Abstract
The paper presents the experimental validation of two mathematical models describing biomass powders compaction (a model that expresses the final density of pellets as determined by the final pressure applied during the process, the initial material moisture and the initial density of the material, but also a mathematical model obtained through dimensional analysis, using Π theorem, expressing the density of pellets as determined by pressure, heat, the initial density of the material, the pelleting speed of and the initial volume of the material), through experimental researches using a ring die pelleting equipment. The results showed a strong correlation between the data estimated theoretically and the experimental data, but also a strong influence of biomass material initial moisture on the density of the pellets obtained.
