The cold compaction of several mineral powders
- 26 Downloads
Four mineral powders with widely different mechanical properties have been studied in prolonged cold compaction. An analysis of the time-dependent deformation has been attempted by splitting the finite strain into two components, one a linear function of time. A single compaction equation has been developed and applied to all four powders. The empirical constants of this equation have been examined, proposals concerning the mechanism of compaction under the prolonged application of pressure have been advanced and a correlation between the empirical parameters and the mechanical constants of the materials has been attempted. Suggestions for future work have been made.
