An internal batch mixing machine (20) includes a mixing chamber and oppositely driven first and second rotors (22, 24). The first rotor has a pair of lobes located in its first and third quadrants (96, 98; 100', 102'), while the second rotor has a pair of lobes (120, 122; 124', 126') located in its second and fourth quadrants. One of the lobes (96, 98) of each pair is longer than the other, and extends downstream at an acute co-helix angle toward the other lobe (98, 116'). The leading end of the long lobe is near one end of its rotor, and the short lobe is at the other end. Material adjacent the longer lobe are pushed away from its end and toward the other end of that rotor. Additionally, the trailing ends of each pair of lobes forms a space which causes confluent material to be squeezed between the trailing ends thereby adding turbulence to further mix the material.
Cette machine (20) de mélange interne de lots comprend une chambre de mélange et des premier et second rotors (22, 24) entraînés de manière opposée. Le premier rotor présente une paire de lobes, située dans ses premier et troisième quadrants (96, 98; 100', 102') tandis que le second rotor présente une paire de lobes (120, 122; 124', 126'), située dans ses second et quatrième quadrants. L'un des lobes (96, 98) de chaque paire est plus long que l'autre et s'étend vers l'aval en formant un angle aigu vers l'autre lobe (98, 116'). Le bord d'attaque du lobe long est proche d'une extrémité de son rotor, le lobe court se situant au niveau de l'autre extrémité. Les matières adjacentes au lobe le plus long sont poussées vers l'extérieur à partir de l'extrémité de ce lobe, en direction de l'autre extrémité du rotor. En outre, les bords de fuite de chaque paire de lobes forment un espace qui provoque l'écrasement des matières confluant entre ces bords de fuite, ajoutant ainsi une turbulence destinée à mélanger encore plus intimement les lots.
