Abstract
The 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.
Claims18
An oscillating ball mill comprising a driving system, a grinding jar, a bearing system, and an elastic system, wherein said driving system and said elastic system are in direct contact with said grinding jar, said elastic system compensates the inertial forces resulting from the operation of said driving system, and the grinding jar motion is substantially along an axis.
