Raw coal refers to the coal extracted from the ground or underground gross coal after screening and processing to remove gangue, pyrite and so on. Unwashed and unprocessed gross coal produced from coal mines is also called raw coal. Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and is a very important energy source. It can be classified as peat, lignite, bituminous coal and anthracite according to its degree of carbonisation.

Investment prospect of raw coal

1, coal for power generation: about 1/3 of China's coal is used to generate electricity at present the average power consumption of standard coal 370g/(kW-h) or so power plants use the calorific value of coal to transform thermal energy into electrical energy;

2, mostly used in steelmaking. It is the main raw material for the production of steel and other industries, the steel industry has been described as the basic food;

3, building materials with coal: about l0% of the coal used in power on the cement coal used in large quantities followed by glass, bricks, tiles and so on;

4, industrial boiler coal: in addition to thermal power plants and large-scale heating boilers, general enterprises and heating industrial boilers with a wide range of models and large number of large and dispersed coal consumption accounted for about 30% of the power coal;

5、Living coal: the amount of living coal is also larger about 20% of fuel coal;

6、Metallurgical power coal: metallurgical power coal is mainly used for sintering and blast furnace blowing with anthracite coal and its amount of power coal consumption of 1%.

Raw Coal Processing Crushing and Grinding

Large lumps of coal are first crushed by jaw crusher or impact crusher, to be suitable for the size of the mill feed size, and then the crushed material with suitable particle size will be sent to Raymond mill, high pressure mill and other milling equipment using conveyor equipment, and the lumps of coal particles will be ground and graded in the mill, and the qualified powder will be collected through the classifier, and the unqualified powder will be regraded.
