I-) FGX SERIES COMPOUND DRY COAL CLEANING SYSTEMS

. DRY CLEANING SYSTEM FOR COAL

Coal extraction typically results in the recovery of “pure rock” that ranges from small to very large quantities.Removal of relatively pure rock from raw coal is referred to as deshaling.The FGX compound dry cleaning seperator. TSM’s proprietary product, is the most popular dry coal deshaling/preparation equipment.The FGX dry cleaning process employs the seperation princible of an autogeneous medium and a table concentrator. Three produt streams, i.e., deshaled product /concentrate , middlings and tailing streams are obtained through this process.Two dust collection systems are employed to prevent dust from being emitted into the atmosphere.

Since 1995 a series of FGX compound dry cleaning seperators have been developed including our FGX-48A model which boasts of a processing capacity up to 480 tons/hour , the largest dry coal seperator ever reported in the world.

Application of FGX dry coal processing technology

1. Near face deshaling for improved coal mining equipments.
2. Preparation of lignite , the coal liable to undergo size degradation in water and low-rank coal.
3. Removal of pyretic sulfur in high-sulfur coal .
4. Pre-deshaling for steam coal preparation.
5. Coal cleaning in arid and cold area.
6. Recovering coal from refuse stockpiles.

II-) CYCLOJET (New Technology for Jet Flotation)

Cyclojet flotation cell , is a new development of Jet flotation system used for enrichment of coal slimes .With this system there’s no need to mixing or compressed air for flotation. Zonguldak coal slimes is examined with that machine and result is CLEAN COAL with %10-15 ash content, and the tailings ash content is %80-85.

III) HEAVY MEDIA CYCLONES (3 PRODUCT)

Coal separation method with heavy media is successive and because of that , the usage of heavy media cyclones gives a new way for cleaning of coal. For that , heavy media cyclone systems, has got the advantage of high seperation technique , and also its structural design is simple , operating cost is low expense and it is suitable for automation .

Actually, heavy media method is usually a complex process, and the raw coal

needs to be classified by size before.Beside if 3 products are obtained as clean coal, middlings and tailings, then 2 heavy media suspension as with heavy dense and low dense, 2 systematic washing process and so 2 heavy media suspension and 2 different recovery system is required.

Because of these reasons , searches for finding a method with high efficiency easy, with low capital and operating costs but more sensitive separation has started and in the end heavy media systems has been found. The first version of heavy media cyclones is with small diameter, pressured feeding and heavy media cyclones with 3 products. 20 years after the discovery of these, the larger ones has been made with high diameter, gravity feeding; Heavy media cyclones with 3 products.
