Coal Vertical Mill is a mechanical device used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants. Coal pulverized machine is the ideal powder making equipment in electric power industry, metallurgy industry, chemical industry, building construction, coal industry, fireproofing materials making industry and some others. The final product’s fineness of coal pulverized machine can reach 38micron (400mesh).
Coal vertical mills are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 8-12 percent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen (74 micron) and 99.5 per cent passing a 50 mesh screen.
Advantages
1. Force-Feed Lubrication. System Force-feed lubrication system extends the service life of bearing by 2.5 times.
2. Maximum Particle Fineness. Traditional roller mill either uses a static separator or dynamic separator to separate fine powder from coarse particles.Vertical coal mill brings together both types of separators for more efficient, adjustable material separation.
3. 20-40% Electricity Savings. Vertical coal mill uses 20% to 40% less electricity than a traditional air-swept ball mill for the same amount of grinding task.
4. Great Drying Performance. Air-swept milling method allows our mill to handle coals of up to 10% moisture content via varying its air flow rate and temperature.
