Attrition of Bulk Particulate Solids

Preamble

The work reported here falls into three distinct areas. Part A provides a review of attrition and an appraisal of existing test methods. Part B presents the results of work on the behaviour of alumina particles in the annular attrition cell and in single particle crushing experiments and associated tests. Part C is concerned with developing insight into attrition kinetics by initial tests in the annular shear cell. The immediate goal was a clarification of the effect of molecular weight on the attrition of high density poly- ethylene.
