In this paper, we will present the research findings concerning relationships between technological and material parameters during densification of cherry tree sawdust. In general during in the biomass densification process technological and material variables influence this process and thus the final briquettes quality. The main goal of presented experimental research is to determine the impact and relationship between compression pressure and particle size. These variables are influencing lonely treatment, densification and also the combustion of final briquettes from cherry tree sawdust. The abovementioned impact of these variables can be observed during densification in the quality indicators. Experimental research findings were obtained using single-axis densification. The influence of the particle size interacting with compression pressure on the final density was determined. The experimental research findings presented here should prove the significance in briquette production and also in the engineering of densification machines.
