A method is disclosed for producing elastomer compounds for use in the production of rubbers. At least one elastomer to be processed for the production of an elastomer mixture can be slowly added to a mixer/extruder and is mixed and plasticized and/or masticated (melted) while it passes through the mixer/extruder. The elastomer, when slowly added to the mixer/extruder, can be present in a fluid medium in an evenly distributed form.

Elastomer mixtures for rubber manufacture

A device for dosing and/or mixing highly viscous and non-flowable materials, especially pigment pastes. The device includes a funnel which revolves about its own axis and a twin screw arranged inside the funnel. The twin screw arranged in a horizontal position in the funnel and contacts the interior wall thereof. This arrangement ensures that all moveable parts of the device mutually strip and clean one another.
