INDUSTRIAL PLANETARY MILL FOR PRODUCING NANOMATERIALS USING MECHANOCHEMICAL PROCESSES

摘要

An industrial mill for the production of materials having a nanometric and/or micrometric grain size using mechanochemical processes is characterized in that it comprises, in combination, a rotating assembly (G) with two or more jars (3) designed to rotate about a central vertical axis (A) of the rotating assembly itself and about their own axis of vertical symmetry (B) via a purposely designed kinematic chain of transmissions and gears (4, 5) that transmits to each jar (3) a motion of rotation equal and opposite to the rotation of the rotating assembly (G) to obtain triggering of the rotations of grinding masses purposely provided inside the jars (3). In this way, the jars (3) that contain the material to be ground move without ever loosing the orientation with respect to a reference system external to the rotating assembly (G), and grinding via said grinding masses inside the jars (3) takes place substantially by friction and not by impact. Said jars (3) are uniformly distributed about the central vertical axis of rotation (A) of the rotating assembly (G).
