FIELD: kneading machines.
SUBSTANCE: in kneading rotors (4, 5), angle (θL) of twisting of long blade (13-15) that makes up kneading blades (13-18) has a value between 38 degrees and 53 degrees inclusive. Long blade (13-15) includes, between the long blades and the inner surface of the case, vertices (from 13a to 15b) of the blades, arranged to form, along the longitudinal direction of the blade, first radial gap (L) at the vertex and second radial gap (S) at the vertex, which is narrower than the first one (L), in width. Central angle (θc) of long blade (13-15) forming second radial gap (S) at the vertex is between 5 degrees and 10 degrees inclusive.
EFFECT: invention provides an improvement in the efficiency of plasticization of the kneaded material and an increase in the productivity of obtaining the kneaded product.
