The plant feed is screened to separate the coarser particles into two size fractions, that is, 152 × 16 mm and 16 × 1 mm to be treated by heavy medium vessel (HMV) and heavy medium cyclone (HMC ...

 — 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.

 — ABSTRACT The conventional flowsheet of coal washing plants includes sequential units where different coal size fractions are washed. Generally, coal washeries include dense medium vessels/drums and cylones for coarse and intermediate sizes as well as spirals and flotation units for fine/ultrafine fractions. Three product-dense medium …
