Calcined Kaolin - NETZSCH Grinding Dispersing

Calcined kaolin is a powdered white non-plastic material. Kaolin is pure clay mineral, having a fired chemistry of 1 part Al 2 O 3 and 2 parts SiO 2. But the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity. Al 2 O 3 is essential to the chemistry of the vast majority of glazes and kaolin is ...

dry grinding of calcined kaolin

The resultant calcined kaolin clay product is then dry milled in a media mill using a work input of from about 100 to 160 hp-hr/ton of dry clay. Prior to the calcined product being dry milled, an effective amount of a dry grinding aid is applied by an appli ion means, preferably by spraying the grinding aid onto the calcined kaolin clay product.
