Both Spiral Classifier and Hydro-cyclone are classifiers. The classifiers consist of four types generally, Raising Water Hydro-classifier, Cone Classifier, Centrifugal Classifier(Hydro-cyclone), Mechanical Classifier(Rake Classifier, Spiral Classifier, Tank Classifier). The reason why we take these two classifiers, for instance, is that they are main classifiers in the mine plant nowadays. In the following, we will compare the two equipment in detail. Spiral Classifier is one of the Mechanical Classifiers, made of a U-shaped water tank, Spiral Device, Transmission Device, Lift-Fall Equipment, Axial Bearing and other parts. The working principle of Spiral Classifier is that slurry grind-ed from the feeder of the Spiral Classifier to U-shaped tank, and the light fine particles will be floated in the surface of slurry through the constant working spiral device, then the particles run over from the overflow weir. Finally, the coarse heavy particles are set in the...
