Screw Classifiers. Screw classifiers such as the Akins and Wemco consist of a semi-cylindrical trough, usually set at a slope of from 2½ to 3½- in. per ft., in which rotates a helix or spiral at from 2 to 8 …
The principal area of application is the recovery and concentration of minerals from pulp streams that contain more than 10% and as high as 90% by weight of very heavy minerals (VHM). The HG10 spiral separator is generally used in a cleaner duty. For high density feed, however, such as iron ore, the HG10 is also suitable as a rougher spiral.

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …
The spiral classifier is characterized by simple structure, easy operation, large installation slope of the groove, easy configuration, and continuous discharge of sediment. However, often mixed with monomeric heavy minerals, the sediment needs to be returned to the mill for regrinding, which may cause overcrushing and reduce the …

Submerged type – there are 4-5 spiral blades at the end of the overflow , all submerged in the pulp. This kind of classifier has a larger settlement area and a deep classification pool, and the agitation of the spiral has little effect on the surface of the pulp. Therefore, the grading surface is stable, and the overflow is large and fine.
The goal of the study was to access the influence of operational parameters such as spiral speed, feed References tonnage rate and washing time on the performance of the Spiral classifier installed at Ghana Gupta A. and Yan S. D. (2006), Mineral Manganese Company (GMC) and improve on the Processing Design and Operation: An manganese grade.
Rake Spiral Classifier: Tujuan Cara Kerja Rumus Circulating Load Ratio Overflow Underflow. Pengertian Classifier: Classsifier merupakan alat yang digunakan untuk pemisahan partikel (mineral bijih) berdasarkan pada kecepatan pengendapan di dalam fluida. Kecepatan pengendapan suatu partikel tergantung pada ukuran, bentuk dan density.
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't 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 …
