Particle properties of pulverized coal are made of different sizes, irregularly shaped particles composed of flour, generally pulverized coal particle diameter range 0-1000um, most of the particles 20-50um; the less dense pulverized coal density, new polished pulverized coal bulk density had about (0.45-0.5) t / m3, stored after a certain time a bulk density (0.8-0.9) t / m3; pulverized coal particles having fluidity very fine, per unit mass of pulverized coal with more large surface area, the surface can absorb a lot of air, so that it has fluidity. This feature enables easy pneumatic conveying of pulverized coal, pulverized coal gravity disadvantage is easy to form and easy to leakage of powder when the device is not tight.
Pulverized coal processing production process
Equipment produced by the company finished pulverized materials, grain type and particle size uniformity, generally pulverized coal particle diameter range 0-1000um, most of the particles 20-50um while equipment high output, low energy consumption, coal is processed preferred equipment.
Mineral processing, bulk material from the crusher, For the primary crusher.
Materials after primary crushing, transferred to impact crusher or cone crusher for secondary crusher.
After post-secondary crusher and material, to meet the requirements, The material transfer have mill for grinding flour, failed The material has a belt conveyor wandering around twelve crushing process, Until compliance with the requirements then there were flour mill.
The final production of the finished materials deposited by the appropriate local party custody.
Particle properties of pulverized coal are made of different sizes, irregularly shaped particles composed of flour, generally pulverized coal particle diameter range 0-1000um, most of the particles 20-50um; the less dense pulverized coal density of about (0.45 -0.5) t / m3, stored after a certain time a bulk density (0.8-0.9) t / m3; pulverized coal milling equipment usually use mill or speed milling machines.
The milling machine widely used in metallurgy, building fillers, cosmetics, chemicals and other industries, which has produced great economic and social benefits.
Widely used in paint, paper, paint, rubber, plastics, fillers, cosmetics, chemicals and other industries.
China is rich in coal resources, in addition to Shanghai to other provinces and regions are distributed, but the distribution is very uneven. In the Greater Xing'an Mountains in northern China - between the Taihang Mountains, the Helan Mountain area, including geographical scope is greater than 100 billion tons of coal resources, more than Inner Mongolia, Shanxi, Shaanxi, Ningxia, Gansu, Henan and 6 all or most provinces, is China's coal resources centralized distribution area, which accounts for about 50% of the national resources of coal resources, accounting for over 55% of China's coal resources in northern regions. In southern China, mainly coal resources in Guizhou, Yunnan and Sichuan provinces, three provinces of coal resources and the 352.574 billion tons, accounting for 91.47 percent of China Southern's coal resources; proven ownership of resources also accounted for the South China proved retain more than 90% the amount of resources. "Eleventh Five-Year" period is the restructuring of the coal industry, the best period of industrial restructuring. Coal is China's basic energy in the primary energy mix accounted for about 70%. "Eleventh Five-Year" plan proposed further established the "coal-based, pluralistic development," the basic strategy, laid the foundation for the prosperous development of China's coal industry.
