  • Patent number: 11872723
    Abstract: A process for producing a rubber mixture in a mixing apparatus having at least one mixing chamber (4, 4?) in which rotors (5) are disposed, wherein a plant control system process parameters (especially the speed of the rotors (5), the suction output of a suction device (13, 14, 15) and the mixing time) are controlled by open- and closed-loop control is provided, wherein at least one rubber is mixed in the mixing chamber with at least one filler, especially silica, preferably with addition of at least one coupling agent, especially a silane, and wherein the gas mixture present in and above the mixing chamber is sucked out by the suction device, wherein volatile organic compounds, especially alcoholic gases, present in the gas mixture sucked in are detected continuously, wherein, in the event of exceedance of a concentration of organic compounds in the gas mixture sucked in that has been defined as the control limit, the concentration measured is employed as control variable in the plant control system for clos

  • Patent number: 11141883
    Abstract: The invention is directed to an apparatus for making a finished rubber mixture which includes a reactive additive. The apparatus includes a tandem mixer with an upper machine having an upper mixing chamber and a lower machine having a lower mixing chamber. The lower mixing chamber is larger than the upper mixing chamber and there are rotors disposed in each mixing chamber. Mixture components are introduced into the lower mixing chamber via a loading shaft of a loading unit. The loading unit has at least two metering devices, a cutting or preheating unit connected upstream of a metering device and a first conveyor belt to the loading shaft. All conveyor belts of the apparatus can be switched on and off automatically, such that mixture components weighed in can be held in a “wait position” thereon.
