Size reduction and mixing mill, for bulk materials, has vertical gravity feed flowing parallel to axis of mill rotor

摘要

A vertical cylindrical casing (32), with at least one top feed inlet (16,18) and a bottom outlet (24), is supported by a structure (12), and has a central vertical drive shaft (46) to which are attached radially extending rotor elements (68). The casing may be mounted on pneumatic bellows to permit raising and lowering in order to clean the wall in conjunction with the rotor. An independent claim is included for the rotor elements, which may be chains and may be attached to a removable sleeve (52).
