Al O Ball Milling System
Al O Ball Milling System. magnetic separator. The natural ferrite microparticles were synthesized by high energy ball milling in a Restch planetary ball mill with tungsten carbide balls and jars. A ball-to-powder ratio of 201, a milling rotation speed of 200 rpm and a milling time of 2, 4, and 6 h were used in the experiments.Cu-Al Al 251 2 O 3 cermet synthesized by reactive ball milling of CuO-Al system powders, are different and depend on the initial amount of aluminium in the mixture. Fig. 2 shows XRD patterns of the mechanochemically synthe-sized composite powders produced at different stages of milling mixture with 27.4 of Al. After 2h.
