coal powder preparation station is a system for making coal powder of a certain particle size. The processed coal powder (usually 200 mesh) can be used as fuel for industrial boiler , steel mills, lime kilns, metallurgy plants, coal chemical industry and other fields.
1. Coal Powder Boiler Coal Powder Preparation
After the renovation is completed, the combustion efficiency of the coal pulverized boiler will increase and pollutants will be reduced. The desulfurization, denitrification and dust removal devices can be installed, which can improve the combustion efficiency of coal-fired boilers, save fuel, and reduce the emission of harmful gases and dust, reach national energy conservation and emission reduction standards, and at the same time increase corporate benefits.
2. Lime kiln (rotary kiln) coal powder preparation
Lime kiln sintered quicklime has developed to the present, and the ash consumption in metallurgy, chemical industry, and building materials industries is becoming increasingly large, especially in the steel industry, calcium carbide industry, alumina industry and refractory materials industries, the quality requirements for lime are getting higher and higher. The development of modern lime kilns has a higher demand for coal powder, and it also puts forward higher requirements for coal powder processing equipment.
3. Preparation of blast furnace powder spraying
blast furnace powder spraying system has a very wide range of uses in the power, steel and metallurgy industries. In the entire system, the preparation of coal powder is an important link, and the quality of coal powder formed by raw coal through processing determines the operating efficiency of the entire system. Because of the high requirements for coal powder and large output, the traditional coal mill cannot meet its requirements. As a result, more and more customers have turned their attention to new vertical coal mills.
4. Coal Chemical Coal Powder Preparation
Coal Chemical uses coal as raw material, and converts coal into gas, liquid and solid products or semi-products through chemical processing, and then further process it into chemical and energy products, mainly including gasification, liquefaction, dry distillation of coal, as well as tar processing and calcium carbide acetylene chemical, which is also inseparable from the participation of coal mills.
large-scale coal powder vertical mill system integrates crushing, drying, grinding and grading conveying. It realizes the "one-step" powdering process while grinding and drying in the form of two-in-one drying and powder making. It can be used for coal powder preparation systems with an annual output of 50,000 to 600,000 tons (specifically, equipment selection and quotation budget are made based on specific production requirements and output scale). In addition, nitrogen inertization technology is used during the mixing coal powder to prevent coal powder from exploded and increase the safety of the system.
