Spiral classifier is beneficiation equipment. Because of the principle that solid particles with different specific gravity will get different deposition rate in liquid, spiral classifier can realize mechanical classification effectively. This machine takes advantages of simple structure and reliable running.
Applications: Widely used in combine with ball grinder into closed circulation for ore-sand separation in the ore separation plant; classify ore sand and fine sludge in gravity ore separation plant; classify the grain of ore pulp at the metal ore separation process; and remove sludge/water at the ore separation process.
spiral classifier is one of the equipment for mineral separation. It is a kind of equipment for mechanical classification by means of the principle that the proportion of solid particles is different, so the precipitation speed in liquid is different. Spiral Classifier is widely used in different particle ore,grading pulp and process of ore desilter in the concentrator.
2.Simple structure, reliable running and easy operation.
3.Continuous spiral raking.
4.Bolted wear resistant lining plate can extend wear life.
5.The lifting device is of electric and manual mode.
Fine ore pulps are fed into water tank through the feeding opening located in the center of settling zone. Beneath the inclined water tank is the ore pulp classification zone where ore pulps are stirred by low-speed impellers. Fine ore particles are lifted up and then spilled out the overflow opening,coarse ore particles precipitate down to tank bottom and are discharged via discharge opening.The position of the overflow opening is higher than the bearing centre where in the bottom of the screw shaft,and lower than the upper edge of overflow spiral.
