A process of media milling employing a mill having a magnetic circuit of magnetic impellers (11) on a shaft (12), magnetized media, and a magnetizable outer shell (10).

Process of magnetic media milling

Media mill (1) having a magnetic circuit of magnetic impellers (11) on a shaft (12), magnetized media, and a magnetizable outer shell (10) which provides improved efficiency. The impellers (43) are magnetized by being sandwiched between at least two permanent magnets (45) in or on the shaft (42), which magnets have the same polar charge facing each other.
