ABSTRACT
In this paper, we will present the research findings the impact of the particle size in pressing chamber during densification of wooden briquettes. In general during in the biomass densification process technological and material variables influence this process and thus the final briquettes quality. The impact of compression pressure and compression temperature is known very well. The main goal of presented experimental research is to determine the impact and relationship between particle size and pressing conditions. This variable influencing also lonely raw material treatment, densification and also pressing forces distribution into the pressing chamber. The abovementioned impact can be observed during densification in the quality indicators. Research findings presented in this paper are based on a realized experimental research which was done on Faculty of Mechanical Engineering STU in Bratislava. This experimental research was a logical result of and based on authors practical experience and wide theoretical analyses of selected parameters impact. Experimental research findings were obtained using single-axis densification. The influence of the particle size interacting with compression pressure on the final density, and thus also on acting forces size was determined. The experimental research findings presented here should prove the significance in briquette production and also in the engineering of densification machines.
