HIGHLY POROUS GRANULATED CORUNDUM AGGREGATE PREPARED OUT OF ALUMINA-POLYSTYRENE-FOAM MIXTURE. PART 3. THE MACHINE PELLETIZING PROCESS' THEORETICAL BACKGROUND FOR ALUMINA-POLYSTYRENEFOAM MIXTURES

Abstract

The alumina-polysterene-foam mixture's pelletizing process is defined by the physical-mechanical and physical-chemical bonds of the material. Also this process is governed decisively by the molecular and capillare forces which significance is defined by both the specific properties of the pelletized stuff, the layer structure and by the moisture amount. The hydrophilic surface properties of the investigated system were determined and its hydrodynamic tendency to the pelletization was studied. Ill. 3.
