The present invention relates to a grinding media mill (2) for obtaining polyisoprene and/or other apolar materials from raw plant materials, having a drum (4) which is peripherally closed and has a milling chamber (10) that is peripherally closed and located in the interior of the drum (4). The aim of the invention is to create a grinding media mill that enables careful processing of the raw plant materials, on the one hand, but is also variable in processing intensity and throughput time, on the other hand. This aim is achieved, according to the invention, in that the milling chamber (10) is divided into a plurality of sections along the rotation axis (6) by partitions arranged crosswise to the rotation axis (6), the partitions have passage openings through which the ground product mixture can pass from one section into an adjacent section, wherein the passage openings are sized such that they retain the grinding media located in a section, and the motor (8) is provided with an apparatus (38) by means of which the rotational speed of the drum (4) is variably adjustable.

A milling assembly for a ball mill has a housing for refining and separating a substrate and a collection vessel for retaining the refined substrate. The housing includes, in vertical order, a lid, at least one milling vessel for receiving milling balls, and a screen with a refining section and apertures. The collection vessel is releasably mounted to a bottom end of the housing. The housing has an orifice arranged therein. The orifice has a valve for selectively allowing gas to pass between an outside and an inside of the housing in an open position of the valve and to seal the housing against the outside in a closed position of the valve. The milling vessel includes a taper for receiving a sealing screw.
