FGX technology is an innovative, efficient, coal preparation process using air. Typically coal processing is completed with water, which is a very costly and scarce resource requiring stricter permits to operate. The FGX dry coal washing process is proven successful, cost effective, environmentally friendly, and requires only an air quality permit.
Coal Washing Plant. The calculation of the performance of coal washing units that are in common use is not difficult and the principles of making such calculations have been known for many years. The flowsheets to be simulated consist primarily of coal washing units each with a target specific gravity of separation specified for each washing unit.
After washing, the coal can remove a lot of impurities and wash 100Mt of raw coal., can save 9600Mt-km capacity. LZZG washing solutions for Coal washing plant process. LZZG Coal washing plants are mainly used to remove impurities from raw coal or to classify high quality coal and low quality coal.
In coal heneficiation plants, generally sand or heavy liquids or magnetite is used for building stable specific gravity in the circuit. In India, magnetite is used in all coal be.neficiation plants.

4. -Fundamental Movable modular coal preparation system actually is a small dense medium coal washing plant with very compact structure. dense medium system is as same as traditional coal washing plant. It is equiped vibrating screens, dense medium cyclone,magnetic recovery system and other accessory equipments.
Burning huge amounts of coal. Coal plants require enormous amounts of coal. Shockingly: a 1000 MWe coal plant uses 9000 tonnes of coal per day, equivalent to an entire train load (90 cars with 100 tonnes in each!). The amount of coal used during a full year would then require 365 trains, and if each is 3 km long then a single train carrying all of this coal would need to be about 1100 km long ...
