METHOD FOR POWDER CALCINATION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention can be used in pigments production. The method of powders calcination for ceramic pigments production involves powder agglomeration for the purpose of individual powder particles aggregation into structures with greater size and following drying of agglomerated powders. The agglomerates are placed into continuous vertical furnace and let be fallen due to gravitation. The calcinated agglomerates are gathered at the furnace outlet. ^ EFFECT: invention allows using of the starting material in the form of pellets without deterioration of the end-product pigments characteristics, to exclude the clogging up of the calcination tube installed inside the furnace and to provide the easy flow of the powders in the furnace. ^ 8 cl, 1 ex
