Rubber-like material kneading apparatus

摘要

In a rubber-like material kneading apparatus having a pair of rotors with radially outwardly extended long vanes in a chamber, each of the rotors has at least three long vanes which are arranged around a rotary shaft at equal angular intervals in such a manner that the cutting angle formed by the rear surfaces of the long vanes and the tangential lines at the outermost ends of the long vanes is larger than 40 DEG , whereby the rubber-like material can be kneaded with high efficiency.
