ball milling of kaolin in the presence of chemicals

Jul 01, 2017 · The values are acceptable in the ceramics industry. Through ball milling, the intrinsic stratiform structure of the kaolinite was gradually destroyed, the resultant particles became finer, and specific surface area was increased. The Al 3 + ions added could fill the vacancy of Fe 3 + on the kaolinite lattice, promoting the leaching out of Fe 3 +. The results obtained from X-ray energy-dispersive …

us3754712a - preparation of stable suspension of calcined

Method for forming a fluid, concentrated, aqueous suspension of calcined clay which is stable without adding a colloidal thickening agent. A suspension of the calcined kaolin clay containing a minimal amount of a clay deflocculating agent is subjected to wet-milling during which increments of calcined kaolin clay are added until a fluid concentrated suspension of desired high solids content is
