White Pigments Grinding

The agglomerates and aggregates in the clinker can be reduced to pigment fineness by wet or dry grinding. Coarse size reduction should be carried out in hammer mills prior to wet grinding in tube mills (with addition of dispersion agents). The coarse fraction can be removed from the suspension by centrifugation, and recycled to the mills. Another established technology with very low maintenance cost is roller milling with subsequent deagglomeration by wet milling. Hammer mills, cross-beater mills, roller mills, and particularly pendular and steam-jet mills are suitable for dry grinding. Special grinding additives can be used that act as wetting agents during subsequent pigment treatment or improve the dispersibility of untreated pigments.
