Coal comminution and sizing - ScienceDirect

01/01/2013  Sizing of lump coal is carried out by sieving, which is the most effective sizing process at coarse sizes. In the case of rotary breakers, the breaker itself is a rotating sieve that provides positive control of the coal topsize. Coarse sieves tend to be heavily constructed and relatively high capacity.

11.10 Coal Cleaning - US EPA

The primary difference is the severity of operating parameters. The majority of coal cleaning processes use upward currents or pulses of a fluid such as water to fluidize a bed of crushed coal and impurities. The lighter coal particles rise and are removed from the top of the bed. The heavier impurities are removed from the bottom. Coal cleaned in the wet processes then must be dried in the ...

What You Should Know About Metallurgical Coal

21/08/2020  Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces. Heat and pressure cause physical and chemical changes that result in carbon-rich coal.
