Second version of a CRA ING Rotor for the Claas Jaguar. Improvement of the chip size. The particle size distribution of wood chips, along with the moisture content, is one of the main parameters to be taken into account in defining the quality of most wood fuels. The self-propelled forage harvester Claas Jaguar is frequently used for the harvest of poplar for Short Rotation Coppice. The product obtained, however, has a reduced size that negatively affects its storage and the quality of the final fuel. In order to improve the dimensional features of wood chips, the Consiglio per la Ricerca e la sperimentazione in Agricoltura - Unità di Ricerca per l’Ingegneria Agraria, set up a first experimental version of the rotor modifying the standard one. Recently, CRA-ING has designed and produced a second version, representing a further evolution, that has allowed the attainment of wood chips with a higher quality. The present study has compared the particle size distribution and the main dimensional features of the scales yielded by the three rotors (standard, first and second version designed by CRA-ING). The results highlight the net improvement obtained: wood chips of increased size, with a lower apparent density and largely distributed within the interval (16 and 45 mm) characterizing the high grade chips .
