### Spray Drying In Cyclone Separators

A gas-solid cyclone separator is a separation device that separates solid particles from a gas phase by the use of a centrifugal force eld. In traditional spray drying a cyclone separator is often included in a succeeding separation step, after a spray drying chamber. This thesis a study of whether spray drying in cyclone separators is possible.

### Optimization Of Dense Medium Cyclone Plant For The

medium separation should be non-detrimental to the effectiveness of separation in the DMS Fine cyclone plant. Medium characterisation showed that removal of ultra-fines leads to unstable media as indicated by faster settling rates. This would result in medium segregation in the beneficiation cyclone thereby leading to unacceptable high density ...
