A study of hydrocyclone classification of coal fines by ...

The elimination of ultrafine (<10 µm) clay particles is essential to the treatment of abandoned coal-washing plant tailings for the recovery of the remaining coal fraction by enhanced gravity processing. Effective hydrocyclone classification is required to remove this fraction. The highly variable composition and particle size distribution of such wastes creates significant …

Classification of fine coal with a hydrocyclone. The classification performance of a 225-mm hydrocyclone has been investigated. Coal slimes of a nominal 0.5 mm size consist were classified in the separation-ra

Screening and Magnetic Separations for Fine Coal ... - ACARP

Since the early 1990s, there has been considerable development of the technology and equipment available for coal preparation which potentially can overcome the serious limitations identified in fine coal Dense Medium Cyclone (DMC) circuits. These limitations were poor size classification and magnetite recovery.

Hydrocyclone for Coal-Washing Equipment

Hydrocyclone Coal Washers and Operation Hydrocyclone Coal Washers. The hydrocyclone, like the dense-medium cyclone, was developed by the Dutch State Mines (DSM). Essentially, it is a cylindro-conical unit with an included apex angle of up to 120°, much greater than the included apex angle of the dense-medium cyclone.

Hydrocyclones | McLanahan

Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and …
