Krebs Heavy Media Hydrocyclones look like classifying hydrocyclones but they are made specifically to clean coal. A gravimetric separation takes place due to the buoyancy effect of the media forcing the lighter coal solids to the center of the hydrocyclone where they are transported upward and through the vortex finder. The dense mineral matter spirals toward the apex and …

An Evaluation of Heavy Media Control Methods
For the heavy media cyclone (HMC) circuit, several parameters were held constant for all of the evaluations. The circuit involved a 250-ton-per-hour (tph) HMC circuit with 6,000 gallons of 1.60 SG media in the operating sump as the base condition. A single 10-ft long x 36-inch diameter magnetic separator is assumed for the dilute magnetite ...
Evaluation of ground calcite/water heavy media cyclone …
Three ground calcite separation medias of different grain size distributions were tested in a cylindrical cyclone to evaluate density separations at 1.09, 1.18 and 1.27 g/cm 3.The differences in separation recoveries obtained with these medias by density offsets produced due to displacement of separation media solid particles within the cyclone caused by centrifugal …
A Different Approach to Heavy Media Circuits
The systems are popular and, as of April 2011, more than 430 plants (or 70% of the Chinese coking coal washing capacity), were using Guohua technology. The systems integrate multiple technologies based on two types of core products: a gravity-fed, heavy-media cyclone and an associated heavy media cyclone for fine coal separation.
Evaluation of ground calcite/water heavy media cyclone …
Heavy media cyclone separation is considered to be the lowest cost concentration method for precise treatment of large volumes of materials. Unfortunately there is no public information available as to the operating costs of cyclone density separation of plastics. Gent et al. (2011) reported that for density separation of coal, this type of ...
Central Coalfields Limited-CCL
It is based on Heavy media bath & heavy media Cyclone washing technology. Kedla Washery Kedla washery was commissioned in 1997 designed by HSCL with installed capacity of 2.6 MTY of raw coal feed. However, at present Effective/Operative capacity is 1.3 MTY due to ageing. Washing process of Kedla Washery is Jig based.
