A screw extruder, including a barrel having a bore which defines an inner surface. At least one extruder screw (28) is positioned within the bore, each screw (28) further including a central shaft (34) and at least one screw flight (30). Each screw flight (30) further includes a front pushing face (36) and a rear face (38). The profile (40) of each front pushing face (36) acts with the inner surface of the barrel to form a progressively narrowing passage through which material is forced into multiple regions of high elongational and shear stress which act to break down agglomerates of material and thus dispersively mix the material.
L'invention concerne une extrudeuse à vis qui comporte un cylindre présentant un orifice définissant une surface intérieure. Au moins une vis (28) d'extrudeuse est placée dans l'orifice, chaque vis (28) comportant en outre un arbre (34) central et au moins un filet (30) de vis. Chaque filet (30) de vis comporte en outre une face (36) antérieure poussoir et une face postérieure (38). Le profil (40) de chaque face (36) antérieure poussoir coopère avec la surface intérieure du cylindre pour former un passage se rétrécissant progressivement, par lequel de la matière est poussée dans de multiples zones de fortes contraintes d'allongement et de cisaillement dont l'action permet de dissocier des agglomérats de matière, et par conséquent de mélanger la matière de façon dispersive.
