— The main reason was changing amount of material delivered to treatment plant from several exploited coal seams. Currently practically only PG SILESIA uses heavy media cyclones for enrichment. This is an example in which direction modernizations of many technologically old treatment plants should go to.
— The magnetite recovery circuit is a typical circuit similar to most coal washing plants throughout the world. Drain-and-rinse screens are used to recover the medium from clean coal, middlings and tailings. The "drain" sections of the screens are used to drain the medium from coal, which is collected in dense medium sumps.
— UCC had renovated a 1,100 tph preparation plant at Sapphire Coal Co. (Letcher County, Ky.), and added a new 500 tph module into the existing Star Bridge prep plant at Carter Roag Coal Co. (Randolph County, W.Va.). ... The clean product is collected in a sump and pumped to 20-inch cyclones for primary dewatering prior to screen bowl …
— The flow sheet of a typical fine coal cleaning circuit used in coal preparation plants is shown in Fig. 13.2.The underflow stream from the deslime screen which is nominally finer than 1 mm is combined in a sump with recycle streams from sieve bends used to deslime the spiral product.The material from the fine coal sump is pump fed to a …
