The Outotec spiral dewaterer consists basically of an open trough with arrangements for collection of the products. The inlet flow is evenly spread out through a feed distributor. Coarse material settles and is continuously removed by means of the transport spiral. The material will be dewatered by drainage in the upper part of the spiralWeb

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)Web
