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.
