The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry.
The powders were balanced in a glove box under high purity ( wt%) He gas and sealed into a tool steel vial (220 ml in volume) together with 50 toolsteel balls (10 mm in diameter); a balltopowder weight ratio of 40 : 1 was used. The vial was pressurized with 70 bar of H 2, and then mounted on a highenergy ball mill (PM 400, RetschGermany).
Highenergy ballmilling is proven to be an effective technique for manufacturing reactive aluminum nanopowders. The procedure of milling presented in this work allows the elaboration of aluminum powders with specific surface areas around 20 m2/g. The particles have platelet morphology and are
To determine whether particle size reduction and surface modification are uniquely achieved by ultrasonic milling, similar experiments were conducted using a highenergy ball mill. The results are shown in Fig. 3. It is apparent that 200–800 nm particles were produced by ball milling for 48 h (12 times longer than ultrasonic milling).
