METHOD OF PROCESSING NEPHELINE SYENITE POWDER TO PRODUCE AN ULTRA-FINE GRAIN SIZE PRODUCT
The method of converting nepheline syenite particulate feedstock with a grain size profile to an ultra-fine grain finish product for subsequent commercial use, the ultra-fine grain final product has a maximum grain size of less than about 6 microns. The method comprising: providing a dry feedstock with a controlled maximum particle size greater than about 20 microns; grinding the feedstock in a dry state by passing the feedstock vertically downward through a continuous, high-speed stirred ball mill whereby the feedstock is ground into an intermediate powder having a drastically reduced grain size profile than the grain size profile of the feedstock; and passing the intermediate powder from the mill through an air classifier using a rapidly moving high speed air stream moving along a given path to convey the ultra-fine grain product along the path and from the classifier and to allow coarse particulate material including particles larger than the ultra-fine product to be separated and then expelled from the classifier.
