The Influence of Design and Operational Parameters on Microniser Performance

The design of the microniser fluid energy mill has developed since its introduction in 1932. The literature tracing this development is reviewed and earlier work by several researchers concerning the influence of the various operational features is reported upon. The research programme described in this thesis sought to establish the optimum features for maximum comminution efficiency. Using the optimum design the main operational parameters were studied. Fluid injection velocity and pressure of the fluid medium were varied and the influence of these and of the solids to fluid ratio on the comminution process are described. Conclusions are drawn as to the optimum and operational parameters. These parameters have been correlated by dimensional analysis and the analysis is compared with that of other workers in different designs of fluid energy mill. Recommendations for future work are made based on these analyses and on the investigation of design features.
