2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.

Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...

The unit cell discharge goes by gravity to the Heavy-Duty Spiral Classifier for separation into the fine flotation feed and the coarse regrind product. Fine Flotation Circuit. Classifier fines go to a Super Agitator and Conditioner to provide a steady flotation feed and also the necessary reagent conditioning for best flotation results. The ...

Our Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. The single, double or …

Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

Flotation Separation Line. Processing Capacity: 0.18-7 m³/min . Processed Materials: Copper, zinc, nickel, gold and other nonferrous metals, coarse and fine separation of nonmetals like coal, fluorite and talc. Details
