Rotatingly Drivable Grinding Media Mill for Obtaining Polyisoprene and/or Other Apolar Materials

A grinding media mill for obtaining polyisoprene and/or other apolar materials from plant raw materials, the grinding media mill comprising:

• a motor;
• a peripherally closed drum, configured to be driven in rotation about an axis of rotation by the motor;
• the peripherally closed drum comprising a peripherally closed milling chamber located in an interior of the peripherally closed drum and configured to receive grinding media;
• a feed device arranged at a first end of the peripherally closed drum and configured to feed a material mixture to be ground, comprised of solids and a liquid, into the peripherally closed drum through a rotary feedthrough;
• a discharge device arranged at a second end of the peripherally closed drum opposite the first end, the discharge device configured to discharge the material mixture to be ground that has been processed in the peripherally closed milling chamber from the peripherally closed drum;
• the peripherally closed milling chamber divided along the axis of rotation into sections by partitions arranged transversely to the axis of rotation in the interior of the peripherally closed drum, wherein the partitions comprise passage openings through which the material mixture to be ground can pass from one of the sections into a neighboring one of the sections, respectively;
• wherein the passage openings are dimensioned to retain the grinding media in the sections, respectively;
• and
• wherein the motor comprises a device configured to variably adjusted a rotational speed of the peripherally closed drum.
