| 20090268547 | DEVICES, SYSTEMS AND METHODS FOR DRY POWDER PROCESSING - Superfine powder particles (70-400 mesh, mean average) are wetted in a processing unit that disperses the powder by impact with an impeller before substantial contact with a solvent, such as water. The impeller is provided with posts that extend the dispersion zone above the impeller to capture and disperse any powder that may accumulate on the top of the impeller. The impeller is driven by a variable speed motor to adjust the rotational speed of the impeller to increase the efficiency of wetting. Processing may be adapted to wetting of other superfine materials, such as clays. | 10-29-2009 |
