How Circulation Attritors Work 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

The technological process is that water, dispersant and heavy calcium carbonate powder are first mixed and dispersed via stirring and then sand ground. The dispersant used is a mixture of sodium polyacrylate of 1000-2000 molecular weight in 20-40% and water in 60-80%, and the ratio between dispersant and heavy calcium carbonate is 5-40 to 1000.
