A relationship is shown between energy requirements and properties of biomass, which is a quite variable material.The relationship between comminution machinery and energy which is necessary for the process is highlighted. The derivation of the model is focused on chipping, but it is generally possible to make it available for both different types of biomass (f. ex. agricultural residues)and different types of comminution machinery (f. ex. hammermills) by using different material properties adju 606 $aBiomass energy$vCongresses 608 $aElectronic books. 615 0$aBiomass energy 676 $a662.8 700 $aNiedzwiecki$b Lukasz$0989073 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910464368303321 996 $aGuide to Biomass comminution$92261926 997 $aUNINA
