POWDER MIXING METHOD FOR GRINDING FACILITIES

摘要

PURPOSE:To mix well and eliminate a mixer such as a paddle mixer or the like by putting other kinds of power into powder flying over in the air current and dispersing therein. CONSTITUTION:Air current containing powder discharged out of one grinding machine 13 of a plurality of grinding machines is recovered and transferred to a cyclone 14 with powder from a plurality of grinding machines 5 and 13 to grind different kinds of materials. Powder ground by another grinding machine 5 is put into a conveying line 23, and recovered by a recovering cyclone 14 after being mixed by air current in said conveying line 23. As a result, powder of an adequate mixing degree can be prepared. As a special mixer such as a paddle mixer or the like is not necessary to be provided and the grinding device can be simplified and reduced in its cost.
