Humphrey's coal spirals are commonly used to process coal in the size range of approximately mm. It consists of a corkscrewshaped device that selectively segregates coal from waste rock when particles move in the flowing film along the helical trough . The mixture of water and ground particles is gravity fed from the top then flow ...
