Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The spiral classifier is one of the size classifying equipment for the mining industry. It is a kind of equipment for mineral classification based on the principle that the specific gravity of solid particles is different and the speed of precipitation in the liquid is different.
Spiral Classifier. Spiral Classifier is a traditional type of classification equipment, mainly for metal mineral processing for the slurry density and particle size on the wet grade, mining operations could also be used in the flow desliming. Model: Submerged series and High series. Spiral Diameter: 300 3000mm. Sink Length: 3000 14300mm
According to the height of overflow , spiral classifier can be divided into high spiral classifier, low spiral classifier and submerged spiral classifier.

According to the number of screw shift, the spiral classifier can be divided into single spiral classifier and double spiral classifier. The classifying performance of the them is basically same,but the double spiral classifier is much better than the single spiral classifier at the return sand treatment capacity, overflow treatment capacity, screw diameter. Besides, the price of double spiral classifier is far higher than the single spiral classifier, which is more suitable for working with largegrinding mill. Mineral processing experts suggest that the single spiral classifier should be selected as far as possible under the determined processing capacity. According to statistics, the working load of the double spiral classifier is 0.6 0.75 times than that of the single spiral classifier, and the efficiency is relatively low. Therefore, the appropriate screw speed and number must be determined according to the processing capacity.
All types of classifiers mentioned above have their own advantages and have different effects on the classifier. According to the current different classifying requirements, different types of classifier have been optimized to achieve a good classifying effect. The mineral processing plant must clearly grasp the characteristics and working principle of each type of classifier, select it by considering the ideal process flow and production demand.

Spiral Classifier for Mineral Processing. 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.
