ABSTRACT:
A continuous kneading apparatus and method are provided wherein discharge ports are provided at a plurality of positions of the barrel to discharge a kneaded product, and one of the plurality of the discharge ports is selected according to a desired kneading condition so as to discharge the kneaded product from only the selected discharge port. Another continuous kneading apparatus and method are provided wherein a plurality of charging ports are provided at a plurality of positions of the barrel to supply a material to be kneaded into the chamber, and one of the plurality of charging ports is selected according to a desired kneading condition. The kneading apparatuses and methods permit adjustment and control of a viscosity and a dispersion degree of a compounding agent over a wide range, and continuous kneading to achieve significant rationalization of a process for producing a kneaded product.
