The ore smelting business helped develop coal mining in Colorado. The smelters needed fuel for their blast furnaces. After cutting down the nearby forests for wood, the smelter owners began using coke. Coke is coal that is partly burned to remove impurities. The remaining coke burns much hotter than ordinary coal.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.

Industrial Hammermills are not limited to limestone or gypsum — they are known worldwide for processing bauxite, nickel ore, phosphate ore, coal, pet coke, clay, shale, and of course, limestone. How Hammermill Crushers Work. All Universal Hammermills work on three principal reduction methods: impact, shear and attrition.

combination of impact and attrition crushing. In this type of crushing first coal is break due to impact and further scrub between two hard surfaces to get desired coal size. Some crushers are work only on principle of impact crushing. Generally these crushers are used before final crushers. The output size of coal affects the performance of CHP.

made it possible for machines to do work previously done by humans and animals. Mr. Watt used coal to make the steam to run his engine. During the fi rst half of the 1800s, the Industrial Revolution spread to the United States. Steamships and steam-powered railroads were main forms of transportation, and they used coal to fuel their boilers.

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Crushers, grinding mills, and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into two basic types, crushers, and grinders. Industrial crushers are the first level of size reducer; further granularization occurs in grinding mills or pulverizers.

The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. Machines called continuous miners are used to remove the coal. The coal is loaded onto conveyor belts and taken up to the surface for further crushing. A machine called a continuous miner at work at the coal face. Room and pillar mining
