Nano Sizing Via Wet Or Dry Grinding Powderbulk Solids

May 06 2010 The primary reason to select media milling is that the process can produce uniform particle size distribution in the micron and submicron or nanometer range Also drymilled materials that have the tendency to agglomerate when added to liquid may avoid agglomeration by being mixed with a liquid and processed in a wet media mill

Wet Grinding Attritor Circulation Mill Union Process

The circulation grinding Attritor Q machine is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor The unique principle of the Q Attritor is the high circulating pumping rate which results in a faster grind and a narrower particle size distribution
