Coal processing uses physical, mechanical and/or chemical methods, to remove rocks, dirt, ash, sulphur, and other contaminants and unwanted materials to produce high-quality coal for energy in both local and export markets.. Multotec manufactures a complete range of equipment for coal processing plants, from the ROM stockpile to tailings dam, including:

COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power

Evergreen undergoes costly clean up of coal stacks under new air pollution rules. The smokestacks at Evergreen Packaging paper mill in Canton will be significantly cleaner within four years thanks to $50 million in pollution upgrades. The plant's four coal-powered boilers don't have state-of the-art pollution controls.

Bowl mills are employed to pulverize the precrushed raw coal to the required fineness before it is. admitted into the boiler furnace for combustion. The. operating characteristics of bowl mills make it the. best mill available for the direct firing system. of the coal. The best features of all the pulverisers.

Clean Coal Technology. Clean coal technologies (CCTs) are a new generation of advanced coal utilization processes that are designed to enhance both the efficiency and the environmental acceptability of coal extraction, preparation, and use. From: Gasification for Synthetic Fuel Production, 2015.

Coal preparation occurs in three stages: 1 crushing and sizing, or basic cleaning; (2) hydraulic separation, or standard cleaning; and (3) dense (heavy)-medium separation, or complete cleaning. Flotation is an additional process that is increasingly being used during third-stage cleaning to increase recovery and cleaning of fine coal.
