The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further ground by a blown-type Raymond mill equipped ...

In most clays the clay material is kaolinite with the formula (OH)4 Al2 Si2 O5, but other clay minerals occur in small amounts. When I make red art terra sigillata, I ball mill the clay, water and deflocculant for 12 hours before starting the separating process. I then take the mixture out of the ball mill and put it into a see through container.
