It is rich in coal resources. This "black gold" is known as industrial food and has become one of the main energy sources in the world. Coal has been used as industrial fuel for a long time, such as thermal power plants, steel industry, pulverized coal boilers, etc., but it has also brought a series of problems.
In addition to low coal combustion efficiency and large energy waste, coal combustion will produce a large amount of soot and harmful substances such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds and dust, which will cause serious environmental pollution and climate deterioration. In the process of traditional coal combustion, coal gangue will be directly discharged, which not only wastes energy, but also causes environmental pollution. Therefore, coal gangue must be treated before comprehensive utilization.
The key is to improve coal utilization efficiency and realize diversified development. The so-called diversified development refers to expanding the purpose to various uses and transforming the utilization mode into a more economical utilization mode. For example, when pulverized coal is pulverized into powder for combustion, the combustion efficiency of coal can be greatly enhanced, which is the same for coal gangue after crushing and grinding new building materials.
In order to meet the high-tech requirements for coal grinding in the market, SMMVIK Machinery has developed the MTW European trapezoidal mill based on the long-term research and development experience and the suggestions of thousands of users to better meet the needs of coal grinding.
1. Coal gangue powder grinding: coal gangue is grinded into different fineness by MTW European mill, which is used as raw material for power plants, building materials and chemical engineering to realize comprehensive utilization.
2. Coal dust: according to relevant research, pulverized coal can greatly improve the combustion efficiency, improve the operation efficiency of small and medium-sized coal-fired boilers to more than 80%, thereby reducing the emission of toxic gases, that is, the economic environment with double benefits.
3. Coal ash: it is the fine ash collected from the soot from coal combustion and the main solid waste discharged from coal-fired power plants. Coal ash is cheap, but it contains a large amount of active ingredients. Therefore, different kinds of coal ash can be produced after grinding by MTW European mill to meet the secondary utilization requirements of building materials, metallurgy, chemical engineering and other industries.
