Firm Ceramic Bead is specially developed for meeting the requirement of producing calcium carbonate, Kaolin clay, gypsum, ceramic glaze and dye. It is used to mill material with medium viscosity or 50-70% solid content at a linear speed of 11-15 m/s. To use firm ceramic bead can increase solid content, and do not block mesh sieve, high fluidity, without breakage and top-rising.
