A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steamgenerating furnaces of fossil fuel power plants
Coalmill classifier – ResearchGate. Download citation | Coalmill classifier | This patent describes a mill embodying a classifier and operative both to grind material and to separate thereafter the ground material into a larger particle fraction and a product smaller particle fraction comprising: a. a mill housing; b. a materi.
But it was not until 1999/2000 that it was first retrofitted to coal mills in the power industry. The conversion of Preussen Elektra's RP 803X coal mills at Scholven power plant in Germany with LSKS classifiers improved the product fineness from 65% passing 75 micron and 96% passing 300 micron to 66% passing 75 micron and .

in Pulverizer Erosion by mineral particles picked up in the air stream carrying pulverized coal through the mill, classifier, exhauster, and transport pipe is a recognized problem. Erosion can produce holes in steel liners and deep depressions in large section cast parts. There has been success in the industry using ceramic materials.
