In mineral processing operations classification and separation of mixtures of fine and coarse particles and also of lighter and heavier particles may be performed in a wet or dry state Classifiers with raised sides are generally called high or H type classifiers In contrast classifiers with low sides and shallow tanks are known as S
Presently over 200 such units have been installed worldwide in mineral processing applications including silica sand for construction grade foundry and glass making purpose mineral sands and hematite processing along with coal [42] There are very few literature available on this particular classifier and the available literature were
Hydraulic classifiers range from simple V shaped launders with a multiplicity of shallow settling pockets for the discharge of as many roughly sized products to the more elaborate deep pocket machines of the hindered settling type having specially designed construction plates and automatic discharge of spigot Dorrco Sizer In the eight

classification and the types of classifiers used in mineral processing Introduction Size control of particles finer than 1 mm are out of the practical range of conventional screens
Air classifiers separate materials by utilizing a dry process Hydrocyclones on the other hand sort particles in a liquid suspension Air classifiers can be used in aggregates production manufacturing sand industrial minerals production as well as in mining operations Hydrocyclones are most often utilized in mining applications
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 times than that of the single spiral classifier and the efficiency is relatively low
Classifiers have found wide applications in the mineral processing industry In this study a novel enhanced gravity closed spiral classifier is presented This device uses induced centrifugal force to classify particles A functional prototype of the separator was 3D printed to experimentally validate the concept The performance characteristics of the classifier were
In mineral processing this fluid is usually water and wet classification is generally applied to mineral particles that are considered too fine <200 µm to be sorted efficiently by screening As such this chapter will only discuss wet classification Principles; hydrocyclones; sedimentation classifiers; hydraulic classifiers
The separation of solids from liquid by gravity sedimentation is the main methodology that is used in are major components in mine and mineral processing they are available in varied sizes and are custom made as per are usually heavy duty applications which can store enough material to
In most mineral processing circuits comminution is carried out to liberate the valuable minerals prior to subjecting the ore to a recovery process were values are concentrated or extracted Mainza Evertsson Benzer Tavares Powell Rule Plint 2013 Comminution is an energy intensive process and is usually achieved in stages
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
Currently spiral classifiers and hydrocyclone are commonly used classifying equipment in mineral processing plants Before using which classification equipment we must be clear about the
