Experimentation will determine the right conditions to achieve the desired separation in a spiral classifier for a particular material. Overflow from a spiral classifier typically contains from 15% to 25% liquid, while the fines overflow contains from 85% to 75% liquid. Catalog Number Dia x L (inches)
Description of Spiral Classifier Spiral classifier is a mechanical grading equipment which works based on the different proportion of solid particles with different sedimentation rate in the liquid. Fine mineral particles floating in the water to overflow while the coarse mineral particles sink to the bottom, then pushed out by the screw to the

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. Applicable materials
Nov 02, 2020 Spiral classifier is one of the common mineral beneficiation equipment, often used for classification, desliming, dewatering and other operations. There are three main factors that affect the classification effect of the spiral classifier: equipment structure, ore properties and operating. 1.Equipment Structure (1) Classification Area

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 & Exploration Mineral
May 26, 2016 The Hydraulic Classifier is made in 2, 4, 6, and 8 compartments with two sizes of compartments, namely 4″x 4″ and 8″x 8″. The standard units are of steel construction. Capacity depends on specific gravity of the material and range of size taken from each compartment. The 4″x 4″ has a capacity from 5 to 10 tons per compartment in 24
High efficient sand classifier machine spiral screw classifier for sale. Manufacturer: YEES Products Description Sand classifier machine spiral screw classifier Sand classifier machine spiral screw classifier is widely used for ore distribution with ball mill to formed closed-circuit circulation in mine
Hydrogritter Classifier - Optimum Grit Capture and Dewatering • Heavy-walled spiral shaft, with protective wear shoes, up to inch thick Ni-Hard in larger sizes • No tank wear. Spiral is suspended between two bearings, operating with a bed of sand between the screw and the tank, improving dewatering and eliminating tank wear common with

The spiral classifier is one of the equipment in mineral beneficiation plant. The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in the liquid is different
Sep 23, 2019 The spiral classifier is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding efficiency of the grinding mill
The submerged spiral classifier is the one whose spiral blades at the overflow end are completely immersed below the overflow surface. It has a small settlement area and low overflow production capacity, so it is mainly suitable for ore classification with an overflow particle size of 0.15-0.07 mm. It is also used to wash ore for desliming
Jul 09, 2020 Spiral classifier and hydrocyclone are the main equipments for the classification operation of the concentrator. Although the rapid development of the cyclone once made the spiral classifier lose its market, but with the continuous changes in the requirements of the selection plant, it was found that the spiral classifier also has its advantages
Mar 16, 2021 DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required
This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values. Many locations don’t have a ready source of water, so when used as a dewatering screw, the slurry particles are removed from the waste stream
