PURPOSE: To eliminate the adhesion of rubber to the lower part of the inner peripheral surface of the casing of a kneader while reducing the closing inferiority trouble of a discharge door by reducing the gap between short blades and making the height of a connection part less than that of the short blades. CONSTITUTION: Long blades 7-9 and short blades 10-12 are respectively provided by two or more so as to be separated from each other at an equal angle and the cut-in angle formed by the rear surfaces 7a-9a in an advance direction of the long blades 7-9 and the tangential line at the outer end of each of the long blades 7-9 is set to 40 deg. or more. The height in the radius direction of the short blades 10-12 of a rotor is set to a degree not exceeding the height in the radius direction of the long blades 7-9. Further, the height in the radius direction of the mutual connection parts 15-17 of the long and short blades 7-9, 10-12 of the rotor is made less than that of the short blades 10-12. By this constitution, the gap between the short blades is reduced to prevent the generation of a deposit to the inner peripheral surface of a casing and rubber passages are ensured to prevent a kneading time from becoming long. |
