This spiral separator is a combined rougher and cleaner which is particularly suited to duties more demanding than those of conventional coal spirals. The principal area of application is coal treatment where increased levels of high-gravity and near-gravity material in the feed result in a greater demand on the separation duty.

Dry coal beneficiation with sorting systems (de-stoning for greater efficiency); wet drum magnetic separators for traditional processing. Even today, traditional coal beneficiation is performed using coal washing with large amounts of water. It is then necessary to expend considerable energy drying the coal again.
