The basic design of a spiral concentrator has a central column and a spiral trough attached to it with a feeding arrangement at the top such that the feed flows down the channel around the central column. The number of turns varies from 3 to 7 depending on the duty and the type of material being processed (Burt, 1984). Various trough designs ...
