Industrial classifier equipment includes screw classifier equipment, spiral classifier machine,spiral chute equiment, dust collector equipment etc. Screw classifiers or spiral classifiers mainly include four types. They are high weir type single spiral classifier, high weir type double screw classifier, immersed type single spiral classifier and immerse type double screw classifier. We spiral chute is a combination of benefits of a spiral concentrator, a spiral chute, a table concentrator, and a centrifugal ore separator.
This spiral classifier or screw classifier is widely used with a ball mill to classify mineral sands, or classify ore sand and fine silt in gravity mill. It is also applied to classifying granularities in mineral separation, or desCathay and dewatering in ore washing.
Spiral classifier or screw classifier is a kind of classifying machine that classifies big and small mineral granules. Screw classifier or spiral classifier works according to the fact that different granules (with various sizes and weight) sink at different speeds in liquids. It can filter powders grinded from mill and rotate the coarse materials to the feeding hole of the mill and discharge filtered fine materials though the overflow pipe.
Spiral chute is suitable for fine materials of 0.3-0.02 mm granularities, such as iron ore, ilmenite, chromite, pyretic, zirconite, rutile, monazite, xenotime, tungsten ore, tin ore, tantalum ore, colombite ore as well as other nonferrous metal, rare metal and nonmetal minerals of different proportions.
The sand pulp is first send to the two inlets of the spiral chute. After added water for appropriate pulp density, the pulp swirls down and generates a centrifugal force which separates the ores and sands. The ore concentrate flows into the hopper and is collected through a pipeline. The tailings are discharged by a sand pulp. Thus, the whole mineral process is finished.
