EIMCO K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are a partially drained fraction containing the coarse material and a fine fraction ...
Mineral processing spiral classifiers are used to classify the ore sand and the graininess of ore pulp in metal beneficiation and desliming, dewatering and other processes in ore washing operations. This classifier can be used with a ball powder mill and it is a great choice for use in beneficiation plants.
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.
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.
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. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.
