WebIt is developed for concentration of low-grade ores and industrial minerals in slurry form. It works on a combination of solid particle density and its hydrodynamic dragging properties. The spirals consist of a single or double helical conduit or sluice wrapped around a central collection column. WebNov 8, 2016 · If a number of pinched sluices are arranged side by side, with the discharge ends pointed inward, they will form a circular tank with each sluice forming an individual compartment. Removing the sides of each sluice forms a circular tank with an inverted cone for the bottom, a basic Reichert cone.

WebPinched Sluice Concentrator. Pulp of between 50-60% solids enters gently and stratifies as it descends; The materials squeeze into the narrow discharge area. The piling causes the bed to dilate and allows heavy minerals to migrate and move along the bottom. The lighter particles are forced to the top. WebJun 1, 2002 · Performance of a pinched sluice might be viewed as an interaction of two separate processes. These are stratification of heavy minerals while the slurry flows over a pinched sluice and separation of the slurry stream into two products after it leaves the sluice. The quality of stratification as well as position of the splitter defines performance.

WebPinched sluice and cones is an inclined trough made of wood, aluminum, steel, and fiber glass, 60–90 cm long. The channel tapers from about 25 cm in width at the feed end to 3 cm at the discharge end. Feed consisting of 50%–65% solids enters the sluice and stratifies as the particles flow through the sluice. WebAn example of a pinched sluice is the Reichert cone, manufactured by Mineral Technologies, which is a derivative of the older tray pinched sluice separator.
