Highly porous granulated corundum aggregate prepared out of alumina-polystyrene-foam mixture. Part 7. The study of possibility to prepare the hollow corundum pellets

Abstract

Fractional composition of the corundum pellets is defined mostly by the polystyrene foam balls grading, by the mixture moisture, and by the granulation's parameters. The using of the high dynamic packing loading influences negatively on the production quality. The plate' rotation frequency, its angle and the granulation time were established in the article. The conditions of the hollow pellets production on base of the technical alumina were developed.
