Coal

Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus and other elements, it is very important energy, but also metallurgy, an important raw material in the chemical industry, coal is mainly used in power generation, steel, cement, fertilizer, system of oil fields. It can be divided into lignite coal, bituminous coal, anthracite, semi-anthracite and other types.

Coal processing production process

Coal processing depending on the size of the main points of the following machining process - block coal processing grain, 100-200 mesh pulverized coal processing, processing of ultrafine coal powder. The following describes the process flow pulverized 100-200 mesh.

Equipment needed

Coal processed in accordance with its use of technology, roughly milling equipment can be equipped with the following: the European version of Efficient crushing-type milling machine, MTM series, MTW series, LM series vertical milling machine and SCM series ultrafine mill.

Investment prospects

Coal processed in accordance with its use of technology, roughly milling equipment can be equipped with the following: the European version of Efficient crushing-type milling machine, MTM series, MTW series, LM series vertical milling machine and SCM series ultrafine mill.

Application areas

The main use of coal

Coal use is widespread summary of the two main purposes in accordance with its purpose of use: (1) coal (2) coking coal

First, coal main purposes are:

1) coal of power generation: the coal used to generate electricity about one-third of the current average electricity generation coal coal 370g / (kW • h) around the power plant utilizing coal calorific value of the electrical energy into heat;

2) steam locomotive coal: coal power accounts for about 2% of the average coal steam locomotive boiler index 100kg / (• km tonnes) about;

3) Building coal: coal power accounts for about l0% on the amount of coal followed by cement glass, brick, tile, etc;

4) general industrial boilers coal: In addition to thermal power plants and large heating boilers and heating business outside like industrial boilers model range with a large number of coal and dispersed coal accounts for about 30%;

5) Domestic coal: coal is also larger number of life accounts for about 20% of coal fuel;

6) metallurgical coal: metallurgical coal main sintering and blast furnace injection amounts of anthracite coal power amount of 1%.

Second, the main purpose of coking coal have

Although China is rich in coal resources, coking coal coking coal resources is relatively small reserves account for only 27.65% of the total coal reserves, used for steelmaking. It is the main raw material and steel industries, iron and steel industry is the basic food metaphor.
