METHOD AND APPARATUS FOR GRINDING PARTICULATE SOLIDS

摘要

Apparatus and method are provided for grinding particulate solids in a liquid media. A pump means repeatedly circulates the liquid containing solids through conducting means to comminuting means, such as agitated-media mill, through the comminuting means and through conducting means back to the pump means at a rate of at least about 30 and preferably between 50 and 300 volumes of liquid continuum containing solids in the comminuting means per hour. Particulate solid materials having substantially greater particle size uniformity and other superior and unique properties are thus produced.
