Steel plant blast furnace injection coal mill, 200 mesh D85 anthracite grinding powder

In a steel plant, the blast furnace is a crucial component used in the smelting process to produce iron. Coal is one of the primary fuels used to provide heat and reduce the raw materials in the furnace. To optimize the smelting process and improve the efficiency of the blast furnace, it is necessary to inject coal into the furnace at a controlled rate.

The coal mill, also known as a pulverizer, is an essential piece of equipment used to grind the coal into a fine powder before injection. The grinding process ensures that the coal particles are small enough to be easily injected into the furnace and combusted efficiently.

In this context, "200 mesh D85 anthracite grinding powder" refers to the specific type and grade of coal being used. "200 mesh" refers to the particle size of the coal, with a smaller mesh size indicating a finer powder. "D85" is a standardized measure of the coal's particle size distribution, with a higher value indicating a wider range of particle sizes. Anthracite is a type of coal with a high carbon content and low volatile matter, making it suitable for use in the smelting process.

So, in summary, a steel plant blast furnace injection coal mill is used to grind anthracite coal into a fine powder (200 mesh D85) for efficient injection and combustion in the blast furnace during the smelting process.
