Spiral classifiers separate the fine waste material from the oversized material that needs to be sent back to the regrind circuit for further size reduction in ore processing. They also serve a dual purpose as a dewatering screw, when the amount of water on site is at a premium. If you have questions or would like an expert opinion regarding the configuration needed for your project, we are
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesnt lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material
Optimal for dewatering of solids in water treatment systems
the spiral out of the tank. Hydraulic spiral lifting device can be supplied as an option. The drive consists of an electric motor, Vrope drive and speed reducer for reliable operation at low spiral speeds needed for low wear and improved dewatering. operation again. The solids are removed by and dewatered in the discharge spiral and
Spiral pitches (single / double / triple): Number of ribbons is a factor in controlling degree of agitation. Each ribbon of advanced pitch gives greater raking capacity than equivalent ribbon of spiral using lesser pitch. Triple ribbon spiral highly advantageous for slowspeed operations requiring close separations and high raking capacities.
Introduction to spiral classifiers. Fote spiral classifiers or spiral sand washer equipped with ball mill as a closed cycle split ranging system are widely used by the dressing plant to distribute the mineral sand, or it is used by the gravity mill to grade ore and fine clay, to realize the size grading of ore pulp during the metal beneficiation process and to do desliming and dehydration
Xinhai improved the submerged spiral classifier.An automatic elevating apparatus is added to the discharge opening. Submerged spiral classifier with the spiral of overflow end completely immersed below liquid level is applied in classifying ore with particle size 0.15~0.07mm Rotating Speed of Spiral (r/min) Capacity of Sand Return (t/d .

The Spiral Classifier is available with spiral diameters up to 120". These classifiers are built in three models with 100%, 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. All sizes and models are available with single, double or triplepitch spirals. The Spiral Classifier offers the greatest sand raking capacity of any classifier available.
