Aug 06, 2015· View ALL our Spiral Classifiers Models. 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.
The spiral classifier working principle: Fine ore pulps are fed into a water tank through feeding opening located in the center of settling zone. Beneath the inclined a 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
Classification equipment may include ore sorters, gas cyclones, hydrocyclones, rotating trommels, rake classifiers or fluidized classifiers. An important factor in both comminution and sizing operations is the determination of the particle size distribution of the materials being processed, commonly referred to as particle size analysis .
It can process materials such as quartz stone, gold ore, iron ore, copper ore, ore, pulp, fine mud, cement clinker, pyrrhotite, etc. According to the number of spirals, the spiral classifier can be divided into a single spiral classifier and a double spiral classifier.
Oct 15, 2014· A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of the spiral trough where they are recovered as a concentrate by
Very low Fe content iron ore (-17%) is discharged as tailings, while high Fe content iron ore (+52%) is passed to thickener then to double spiral classifier. Large ore particles pass to secondary ball mill to be grinded into products less than 200 mesh in size which will return to secondary thickener. The others pass to cylinder screen.
Material Handling: iron, gold, copper vibrating feeder, jaw crusher, circular vibrating screen, ball mill, spiral classifier, linear vibrating screen, high-frequency vibration screen, spiral chute, jigger, shaking table, etc. zirconium, etc.), which is also used for sorting weak magnetic iron ore, manganese ore and chrome ore. In recent
To improve efficiency, some concentrator Hydro cyclone replace the second spiral classifier. More about Iron Ore GrindingIron Ore Beneficiation Very low grade Iron ore cannot be used in metallurgical plants and needs to be upgraded to increase the iron content and reduce the gangue content. A process adopted to upgrade ore called Beneficiation.
Spiral classifier is widely used in mineral processing plant to form closed cycle way with ball mill for split mineral sand, or used in gravity concentrator to grade ore and fine mud, or the size grading of slurry in ore dressing process as well as desliming, dehydration and other operations in ore washing operations.
