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 LEADER 01317nam a2200373 i 4500 001 991001188089707536 005 20020507184859.0 008 950302s1982 de ||| | eng 020 $a3540111999 035 $ab10813032-39ule_inst 035 $aLE01308415$9ExL 040 $aDip.to Matematica$beng 082 0 $a519.4 084 $aAMS 65-06 084 $aAMS 65-XX 084 $aAMS 65D10 084 $aAMS 65F99 084 $aAMS 65K05 084 $aAMS 65M25 084 $aAMS 65N30 084 $aAMS 65R20 100 1 $aWatson, G.
