Highly Porous Granulated Corundum Filler of Alumina-Foam Polystyrene Mixture. Part 5. Effect of Molding Mixture Fineness and Moisture Content on Filler Granulation Capacity and Physicotechnical Properties 1

摘要

It is established that there are three stages in molding mixture pelletization: nucleus formation, granule growth, and mass transfer between them. Addition of a surfactant improves granulation capacity and reduces molding moisture content, and increases raw granule strength. The fineness of the starting material has a significant effect on capillary reaction forces that are fundamental during molding mixture pelletization.
