HICTECH Dense Medium Cyclones (DMCs) are designed and manufactured to order, ensuring every cyclone is 'fit for purpose' prior to manufacture. The process evaluates the operating conditions of the plant in which the cyclone will be installed. This evaluation provides the required data which is then analysed through a dynamic processing model.
The hydrocyclone overflows contained generally good clean coal products which would require little retreating to remove misplaced high-gravity material. The underflows, however, contained from 63.6 to 36.7 percent of misplaced low-gravity material which would require secondary cleaning to provide acceptable clean coal yields. (Author) Keywords

Results. Over most of the product size range examined, particularly in the range of interest, 80 weight percent passing 100 to 120 microns, high frequency screening with the DF 88 or DF 105 cloths gives higher Q than when the hydrocyclone is used. That the screen and hydrocyclone results are not so different is due to the relatively low ...
The lignite coal tailings were treated by a two-stage concentration scheme for the recovery of fine clean coal.

The Multotec hydrocyclone range comprises cyclone diameters from 25 to 1 400 mm. Most of these diameters can accommodate a range of cone angles, while different vortex finders and spigot diameters are standard for all diameters. The small diameter cyclones, up to 165 mm, are predominately polyurethane, while the larger diameter units can be ...

Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but different specific gravity, or particles of different size but identical specific gravity. Cyclones are also commonly used for dewatering of slurries given that they are much faster throughput …
The authors found that mini-hydrocyclones were capable of MP removal, but a trade-off existed between separation efficiency and concentration ratio. The mini-hydrocyclone was designed using a single cone body and twin tangential feed inlets. The maximum concentration ratio for 10 μm MPs was 2.16.
