S.W.M.S. Spirals are the most technologically advanced Spirals on the market. Spiral concentrators use specific gravity to separate mineral particles simply, efficiently, and cost effectively. The S.W.M.S. Spiral concentrator is primarily designed to treat pulp streams with a medium heavy mineral content in the range up to 15-80% by weight. It comprises of a back-fed feed box, single section helix and a product box. Splitters in the product box divide the main trough dis- charge into concentrate, middlings and tailings.
