Towards a parameter characterising attrition
Two particulate systems, heavy soda ash and a tetra-acetyl-ethylene-diamine agglomerate, have been subjected to attrition in a fluidised bed, a screw pugmill and an annular shear cell. Each of these devices has a different mechanical action on the materials. The attrition in each piece of equipment was characterised using a function developed by Gwyn and, for each material, one characterisation parameter was found to be independent of the mechanical action of the equipment. In addition, a recent treatment of material behaviour developed by Neil and Bridgwater was also found to characterise data from the annular shear cell.
