It is similar in structure to the spiral classifier, except that the blades are in the shape of discontinuous blades. Structure The spiral washing machine is mainly composed of transmission device, spiral, tank body, lower support, overflow trough, etc. It Includes: 1. Transmission Device: It is the power of the spiral work. The spiral rotation ...
In the mineral and coal industry the particles are usually fluidized in water media for gravity classification. The separation is a consequence of the stratification and utilizes hindered settling properties [29].The feed slurry enters into the classifier through a feed well and the water added to the bottom of the spigot column is called teeter water.
Hydrogritter Classifier - Optimum Grit Capture and Dewatering • Heavy-walled spiral shaft, with protective wear shoes, up to ¾ 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 MG12 spiral gave us the opportunity to achieve maximum recovery from a multi-stage circuit making the plant smaller and easier to float. The spiral bank modules dropped into and integrated with the plant structure enabling a …
the nine types of classifiers described in this paper there are individual limits of application, as shown in Table I. Mechanical-hydraulic classifiers, equipped with either reciprocating or spiral rakes, are the most widely used and have countless applications. Unit-Type Classifiers Limitations: Unit-type classifiers are commonly
The objective of this report is to understand the principles of classification, and the types of classifiers used in mineral processing. Discover the world's research 25+ million members
Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul. 2.2 Designing of Test Works Prior to test work design, visit to the oxide plant at Ghana Manganese Company (GMC) were made with the aim of getting acclimatize with the current operations at the plant. The Spiral classifier was operated in batch mode.
Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types. They are high type single spiral classifier, high ... for the size grading of slurry in mineral processing plants and for desliming and dewatering
Spiral classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. It is also used for or washing clay sand, silica sand, tailings …
Spiral classifier is widely used in mineral processing plants with a ball mill as a closed-circuit circuit to separate the flow of ore sand, or used in gravity concentrators to grade ore sand and fine mud, and metal beneficiation …
During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...
The spiral classifier is one of the important equipment in the mineral processing process. Its principle is to use the difference in the settling speed of solid particles in the liquid to classify materials. The classification effect of the spiral classifier will directly affect the content of qualified products in the returned sand, thus affecting […]

Spiral Classifiers provide greater sand raking capacity, have improved gear reducer and drive arrangement. Available in three degrees of submergence, in three tank styles, single, double or triple pitch spiral, with either manual or hydraulic lifting device. If you are looking for an affordable screw classifier manufacturer, contact us.
Rake classifiers are also used for close circuit grinding. Both rake and spiral classifiers are more efficient in classifying the coarse particles. But they are very costly for installation. In these classifiers the separation achieved is distinct. Dry classifiers. Dry classifiers are based on the principle that separation by air fluidization.
