HIGH BULK DENSITY CALCINED CLAY

Calcined clay pigments in a form for bulk shipment are prepared by the addition of water to dry particles to form plastic aggregates which are then increased in size and rounded, as by disc pelletizing, and air dried to produce a dust free, free-flowing, high bulk density material. On fabrique des p...

Zusammenfassung:	Calcined clay pigments in a form for bulk shipment are prepared by the addition of water to dry particles to form plastic aggregates which are then increased in size and rounded, as by disc pelletizing, and air dried to produce a dust free, free-flowing, high bulk density material. On fabrique des pigments à base d'argile calcinée, destinés au conditionnement en vrac, en ajoutant de l'eau aux particules sèches de façon à former des agrégats souples, on augmente la taille des agrégats et on les arrondit, par exemple par agglomération en disques, puis on les fait sécher à l'air de façon à obtenir un matériau ayant une masse volumique en vrac élevée, dépourvu de poussière et s'écoulant librement.
