Coal dust is a type of fine coal powder ground by coal grinding mill, size range ~, and most of powder''s size range 20~50μm. Pulverized coal processed by grinding machine could be fully burned, use ratio very high, and we have provided technical support for many power plant.
The grinding process of coal is a process in which the mechanical force continuously breaks the chemical bonds in the coal. A large number of covalent bonds in the coal undergo homolytic cracking under the action of mechanical forces, resulting in a large amount of active free radicals. This process can be confirmed by the change of free ...
In coalfired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
