Buy NowAdvantages of Ball Mills. It produces very fine powder (particle size less than or equal to 10 microns). It is suitable for milling toxic materials since it can be used in a completely enclosed form. Has a wide application. It can be used for continuous operation. It is used in milling highly abrasive materials.

Buy NowResults and discussion. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate.
