Kaolin or kaolinite is alumina silicate clay that was formed from the weathering of igneous rocks in moist and warm climate regions.
Kaolin is used in paper filler and coatings, in cosmetics, in ceramics as well as ceramic proppants, in addition to many filler or absorbent applications.
HCPS can provide the milling of kaolin with our Mikro ACM air classifying mill systems. The particle size is controlled by the internal air classifier, to provide sharp particle size distributions. Various classifier designs are available, to produce from coarse (100 mesh) product down to a fineness of 400 mesh product or a D50 of less than 5 microns.
An alternate to the Hosokawa ACM for coarser grade Kaolin is the Mikro Pulverizer Hammer Mill. The Mikro Pulverizer uses swing-hammers with interchangeable screen liners to produce a variety of products from 50 mesh to 150 mesh products.
