subject: What Crushing Machine Should Be Chosen For Crushing Coal? [print this page] Coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide, Coal is extracted from the ground by mining, either underground or in open pits. Coal is primarily used as a solid fuel to produce electricity and heat through combustion. Coal is the workhorse of the nations electric power industry. The USA consumes about 14% of the world total, using 90% of it for generation of electricity, Coal-fired electric generating plants are the cornerstone of the nations central power system.
Coal is the most important solid fuel is a combustible organic rock. It is a luxuriant growth of certain plants geological time, in a suitable geological environment, gradually accumulate into a thick layer, and buried at the bottom or sediment, after a long geological age of the formation of natural coalification. The geological time in the world in order to Carboniferous, Permian, Jurassic and Tertiary strata in coal most important coal-forming age. Carbon content of coal is generally 46 to 97%, brown to black, with dark to metallic luster. According to the different coal rank, coal can be divided into peat, lignite, bituminous coal and anthracite four categories.
Though coal has many usages such as gasification, liquefaction, ethanol production, the major usage is used as fuel and coke. In order to make full use of coal and reduce the pollution of the environment, after the coal have been mined, people usually crush the larger coal block to small one by coal crushing plant, use coal mill or coal pulverizer to grind the coal.
In the coal crushing plant, coal crushing can resize the coal stone so that it can be easily handled and processed. For the Mosh hardness of coal is usually under 5, the miners can use jaw crusher, impact crusher, hammer crusher etc. to handle it. After the coal has been crushed, we need vibrating screen to grade the coal by size and then transport the coal via belt conveyor. In this process, dewatering screen is optional to remove water from the product.
Besides, we sugguest you use cone crusher to crush coal.The whole range of the cone crushers enjoys a professional pre and after-sale product support including process simulation and planning services.It is having these Advantages:
1.High performance;
2.Better particle components size;
3.High stability;
4.Convenient cavity cleasing;
5.High reliablity;
6.Convenient maintanance and easy operation:;
7.Low operation cost;
8.Wide application.
