WORM MIXER HIGH-VISCOSITY MATERIALS Russian patent published in 1996 - IPC

FIELD: tyre industry. SUBSTANCE: in mixing zone thread segments with variable depth of channel have length smaller than thread pitch. The value of minimal depth of thread channel of each consequent segment with variable depth of thread channel is chosen in the direction of outgoing end of worm to be smaller than the value of minimal depth of channel of each previous segment with variable depth of thread channel. EFFECT: enhanced quality of reprocessed material due to increase in mixing intensity and to constructive execution of mixer. 1 cl, 8 dwg
