PCT No. PCT/EP93/03000 Sec. 371 Date Apr. 25, 1995 Sec. 102(e) Date Apr. 25, 1995 PCT Filed Oct. 28, 1993 PCT Pub. No. WO94/09907 PCT Pub. Date May 11, 1994The present invention concerns a high energy oscillating ball mill, useful in the preparation of nanophase materials having crystallite sizes of the order of 5 to 20 nm, with high production capacity and consisting of a grinding jar (containing, in the working conditions, the grinding balls and the materials charge to be processed) driven in an alternate regime of motion. Such a grinding jar is elastically constrained in such a way that the inertial forces originated during the oscillations are compensated.
