Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi cylindrical trough inclined to the horizontal. The trough is provided with a slow rotating spiral conveyor and a liquid overflow at the lower end.
The spiral classifier is one of the equipment in mineral beneficiation plant. The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in the liquid is different.
DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes from a sandy sized material. It is well suited for classification, where a two product size split is required.
Spiral classifier for Iron Ore, Copper, Zinc cleaning and processing. September.19,2019. Ore spiral classifier application. Spiral stone classifier is a large scale mining equipment used in black and non ferrous metallurgical mines, steel, metallurgy, chemical industry and building materials to wash ore and stone materials like iron ore sand, copper ore, gold sand, placer sand.
Fig. 3 illustrates the optimum feed conditions for the FM1 fine mineral spiral at a values recovery of 50% viz. low feed rate 0.8 t/h and feed pulp density of 35 36 %solids. The benefits of using the FM1 spiral for the treatment of fine grained silica sand, tin tailings, iron ore and copper were also investigated .
