Highly Porous Granulated Corundum Filler of Alumina-Foam Polystyrene Mixture. Part 7. Study of the Possibility of Preparing Hollow Corundum Granules1

Resumo

The fraction composition of corundum granules is determined mainly by particle size analysis of a foam polystyrene nucleus, mixture moisture content, and granulation parameters. Use of high dynamic compaction loads has an unfavorable effect on product quality. Plate rotation frequency, its inclination angle, and granulation duration are established. The operating sequence for preparing hollow granules based on commercial alumina is established.
