The design of closed spiral classifier (CSC) is inspired by the open spiral separators and hydrocyclones [19], [20]. Feed slurry is passed through a closed rectangular spiral channel at sufficiently high velocity. Due to the induced centrifugal acceleration, heavier or coarser particles migrate faster towards the outer wall leaving behind the ...

Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul. 2.2 Designing of Test Works Prior to test work design, visit to the oxide plant at Ghana Manganese Company (GMC) were made with the aim of getting acclimatize with the current operations at the plant. The Spiral classifier was operated in batch mode.

The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling.
