The first aim of this study was to find out the moisture content of sawdust in drying and briquetting process. The moisture content of sawdust has an effect on output quality. The moisture content and density of output worked out. The second aim of study was to find out how the feeding volume of dried sawdust and the moisture content of output are influencing together the density of output. The moisture content of input is on average 56,8 +/- 2,3 % and it is homogenous. The moisture content of midput is on average 11,2 +/- 7,9 %. Variation is large. The moisture content of output is depending on moisture content of midput. The moisture content of raw material has an effect on output density. The optimum moisture content is 11 % for high density of output. The feeding volume of dried sawdust has also an effect on output density. Low feeding volume increases and high feeding volume decreases density of output. The density of output is on average 951— 1011 kg/m3 depending on briquette press.The energy content of sawdust is 0,68 MWh/loose m3 and the energy content of briquettes is 3,07 MWh/loose m3. The energy content of sawdust becomes five times better in drying and briquetting process.
