LM Vertical Roller Mill For Pulverized Coal

2021-04-22

The main equipment for energy conversion -- boiler, steam turbine and generator, is known as the three main engines of thermal power plants, and the boiler is the most basic energy conversion equipment among the three main engines.AEAUltrafine Grinder, Ultrafine Mill For Sale

The pulverized coal used for boiler combustion is an irregular fine coal particle which is ground into coal powder by the coal mill. The average particle size is 0.05-0.01mm, and the particle size below 20~50μm (micron) accounts for the vast majority. Because pulverized coal particles are very small and the surface is very large, it can absorb a lot of air, and it has the properties of general solids - fluidity.AEAUltrafine Grinder, Ultrafine Mill For Sale

The preparation of pulverized coal refers to the process of processing raw coal into pulverized coal with particle size and moisture content in line with the requirements of blast furnace coal injection.AEAUltrafine Grinder, Ultrafine Mill For Sale

The requirements of blast furnace injection system for pulverized coal are: particle size less than 74μm accounts for more than 80%, moisture is not more than 1%.AEAUltrafine Grinder, Ultrafine Mill For Sale

And it can be arranged outdoors so as to greatly reduce the investment costs.AEAUltrafine Grinder, Ultrafine Mill For Sale

Low Operating CostsAEAUltrafine Grinder, Ultrafine Mill For Sale

Less wear: The roller does not contact the grinding plate directly and the roller and grinding plate are made of high-quality materials. Therefore, they enjoy longer service life and less wear.AEAUltrafine Grinder, Ultrafine Mill For Sale

High efficiency: The grinding rollers can directly grind materials on the grinding plate, featuring lower energy consumption (30% ~40% lower than that of ball mill systems).AEAUltrafine Grinder, Ultrafine Mill For Sale

Strong drying power: The hot air can directly contact materials in the mill. By adjusting the hot air temperature, it can satisfy the grinding demands of materials of different moisture content.AEAUltrafine Grinder, Ultrafine Mill For Sale

Stable performance: A limiting device is provided to prevent direct contact between the roller sleeve and the lining plate of the grinding plate, so that destructive impacts and violent vibration could beAEAUltrafine Grinder, Ultrafine Mill For Sale

High-quality Finished ProductsAEAUltrafine Grinder, Ultrafine Mill For Sale

The materials only stay in the mill for a short time, which can reduce repeated grinding, and facilitate testing and controlling the product particle size and chemical composition as well as stabilizing the product quality. The grinding roller does not directly contact the grinding plate, so the product contains very little iron and the iron contents due to mechanical wear can be easily removed, so that the whiteness and purity of the product can be effectively guaranteed.AEAUltrafine Grinder, Ultrafine Mill For Sale

An efficient dynamic and static combined powder classifier is adopted with the rotor speed adjustable, so that higher classification efficiency and top-quality finished products could be ensured to satisfy different requirements for fineness.AEAUltrafine Grinder, Ultrafine Mill For Sale
