Abstract
A process and apparatus for coal gasification plant feedstock preparation. A raw feedstock slurry is fed to a hydrocyclone which separates and provides a primary carbonaceous-rich overflow. The primary overflow is further separated by a dewatering screen into a secondary carbonaceous-rich overflow and a media bleed slurry. The secondary overflow is crushed by a crusher and a portion of the media bleed slurry is added to the crushed secondary overflow for subsequent milling and conditioning.
