COAL MINING EQUIPMENTS

Coal Mining Equipment

Coal is one of the worlds most plentiful fossil fuels, and has been burned for centuries as a source of heat and energy. Electricity is the main use. Another major use of coal is in iron and steelmaking. The iron industry uses coke ovens to melt iron ore. Coke, an almost pure carbon residue of coal, is used as a fuel in smelting metals. Coal is also used by other industries. The paper, brick, limestone, and cement industries all use coal to make their products.
Coal mining

Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. The particular mining method chosen depends on surface terrain conditions, coal layering, access, and reclamation of laws. Surface mining is regulated by a set of rules governing the recovery and relegation of original topography, while underground mining is mostly regulated by safety concerns. If the coal seams are shallow, and close together, then surface mining is considered. However, if the seams are thick (greater than five feet thick), and deeperbetween 200 and 2500 feet deep), then underground mining is considered.
Coal mining equipment

No matter what mining methods, after coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove other rocks and dirt, ash, sulfur, and unwanted materials, increasing the heating value of the coal. The common coal mining equipment using in this plant is washing machine.

coal mining equipmentGeneral, in order to increase the heating value of the coal, we usually make coal into powder through crushing and grinding process. In this process, we use coal crushing plant to crush coal into small size. In coal crushing plant, jaw crusher is primary crusher, then impact crusher is secondary crusher, the final crusher is cone crusher. In coal grinding process, which coal mining equipments is usually used ball mill, vertical mill, and ultrafine grinding mill.

Zenith is a coal mining equipment manufacturer in China, and supplies all kinds of coal crushing plant, coal grinding machine for coal industry.
