However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions

Generally used for reducing material to a particle size as low as 180µm (80 mesh) a cone mill produces less dust and heat than alternative forms of milling. The gentle grinding action and quick discharge of correctly sized particles ensures tight particle size distributions (PSDs) are achieved . Reassuring Milling Experience...The applications of mechanically alloyed products are described in Section 16 and the problem of safety hazards in handling fine powders such as those produced by mechanical alloying are discussed in Section 17.
