Vertical Mill Description
Coal Vertical Mill is a mechanical device used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants. 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. Variation of the coal hardness and/or moisture content will effect, up or down, the discharge capacity or the discharge fineness.
To achieve these design considerations it is essential that the grinding elements are in good condition and they maintain a consistent profile. The loss of the grinding profile results in a loss of grinding efficiency, meaning the pulveriser must work harder to achieve an equal result.
Ultimately a point will be reached in which either a loss of capacity or a loss of fineness will result under uniform conditions. Longer lasting, more consistent grinding elements are crucial to pulveriser operation yielding longer operating campaigns, reduced maintenance and a lower overall invested cost.
Application
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.
