摘要

A method for mastication of natural rubber or natural rubber support strength mixtures in a ram-less interior mixer with a in a trough (1) mixing chamber, is accommodated with driveable kneading blades, wherein the filling opening (3) of the trough (1) at the same time the discharge opening, and the trough (1) after the completion of the treatment or by tilting of the mixing process is emptied, with the material to be mixed in the mixing chamber during a period of time of 0,5 to 10 minutes at a positive pressure of from 0,1 to 1 mpa, in particular up to 0,5 mpa, and while heating to a temperature of between 50 and 170°C, in particular to 130°C, is kneaded.
