Analysis and Design of Hemp Fibre Decorticators

decorticators are hammer mill and roll crusher. Hammer mill has the advantage in decorticating short fibres and its capacity is relatively high, while roll crusher is capable of extracting long fibres (Munder and Fürll 2004; Hobson et al. 2000). In some of the main producing areas, hemp fibre extraction is still a labor-intensive work.
