Abstract

An apparatus for producing rubber mixtures, comprising: as a master batcher, a ram kneader than operates in a batch-type process; a ram-less final mixer that is disposed below the ram kneader, also operates in a batch-type process, and has a greater volume capacity than does the ram kneader, with the final mixer having a mixing chamber that is provided with rotors; an essentially vertically disposed transfer channel for the transfer of a master batch from the ram kneader to the mixing chamber of the final mixer; and one or more withdrawal or exhaust openings disposed above the mixing chamber of the final mixer in walls of at least one of the transfer channel and the mixing chamber of the final mixer.
