					3 - Application of Morphi to pulp characterization (slides 17-24) R. Passas, B. Khelifi, G. Tarrajat, C. Caucal (EFPG)

	17 - Refining: study of one length class Variation of the modification factor as a function of °SR, for a given fiber length, in paper pulp refining				18 - Refining: °SR prediction Comparison of calculated and measured °SR in paper pulp refining

	19 - Refining: 100% SW and 100% HW Paper pulp refining. Comparison of calculated and experimental °SR for softwood or hardwood alone				20 - Refining: 50% SW + 50% HW (1)   Distribution of paper pulp fiber length for a 50-50 mixture of softwood and hardwood having the same °SR

	21 - Refining: 50% SW + 50% HW (2) Distribution of paper pulp fiber length for a 50-50 mixture of softwood and hardwood having different °SR: 22 °SR for hardwood and 57 °SR for softwood				22 - Mechanical pulp: shives (1) Inlet: 251 26.1 Screening stage Accept: 29 22.1 Reject: 391 45.7 Legend:   Numer of shives per gram (g-1)   Shive area per gram (mm2.g-1)

	23 - Mechanical pulp: shives (2) Shive area as a function of Sommerville index, after refining and after grinding				24 - Conclusion MorFi is an interesting device to analyze the pulp morphology The values thus obtained allow different applications:      study of the refining stage   study of pulp and mixed pulp   process control
