6 Inclined Conveying Tests
One of the underlying reasons for this investigation was to evaluate the OLDS unit as a potential device for the feeder of filter cake into exhaust gas streams for drying. This process has inherent problems associated with the filter cake becoming compacted prior to discharge to the flue gas causing process difficulties. An equally significant issue is the formation and maintenance of a gas seal to prevent/limit exhaust gases entering work spaces. If using a horizontal screw feeder this involves level detection and cycling of the screw speed. It was the OLDS elevators inability to fully self clear with the free flowing materials that prompted the investigation into inclined conveying.
