A PLANETARY HIGH-ENERGY BALL MILL AND A MILLING METHOD

摘要

A Planetary High-Energy Ball mill is for producing nanosized powders and it includes: (a) a main axis which can not only rotate but also up and Down, (b) a roll-bearing to b e fixed on nether end of the main axis, a revolvable plate to be fixed on the top of the main axis, a nd several able-swing shafts installed in the plate. (c) a plurality of planetary motion mill pots are fixed on the support canisters which are supported by able-swing shafts. (d) A stationary ring which is disposed coaxially with the main axis and serves as the orbit for mill pots. (e) impa ct bars on the bottom of mill pots using magnet technology to disperse deposited powders. The inventi on solves the problems of powders deposited on the bottom of mill pot, avoids tire ruption applied to private shaft which supports mill pots, improves stress distribution. So it capable for industrial-scale producing nanosized powders. The present invention also introduces a milling method for producing a wide variety of nano-scaled ceramic, metal and composite by selecting metal materials from the period table and the ceramic materials from the group of oxide, carbide, nitride, chloride, boride, silicide, sulfite etc .
