A pulverizer hammer mill is a mechanical grinding device that is used for parting distinct types of materials. Coal and mining industry uses this device to pulverize coal for combustion in steam-generating furnaces for fossil fuel power plants. Major types of pulverizer design available in the market are- Low speed pulverizer Medium speed pulverizer High…
To examine the performance of the classifier vanes attached to the mills and the relationship between classifier vane opening and coal fineness, the output of each mill was adjusted to the level achieved when the boiler operated at full load during the experiment. The primary air velocities at the ill m outlets were maintained between 20-25 m·s
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of <100 mesh and 95% <200 mesh, or better.
grind the coal with steel balls in a rotating horizontal cylinder. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill. fTUBE MILL These are slow speed Mills. The Mills are designated as BBD-4772 Where, B Broyer (Name of inventor). B Boulet (French word for Balls). D Direct firing.
The FCM, an air-swept impact mill with integral classifier, grinds to low-micron range with tightest particle size distribution.
There are 2 positions at the extreme. 0 : Means all classifier vanes are fully Open 10 : means all classifier vanes are closed. Based on the fineness analysis, the classifier is set to achieve the desired fineness level. CLASSIFIER SETTING. For optimum mill operation, the classifier pointers should be set between 0 and 3.

effect of the mass flowrate of coal and air, classifier geometry, and the opening of the spiral guide vanes on the coal classification efficiency [5, 6]. It is worth to mention that the optimum quality of classification for coals such as lignite is achieved when 70% of coal particles exiting the classifier is smaller than 75 μm [7, 8] .
The HEP Classifier has the ability to balance the air/coal ratio in each coal pipe served by a classifier, with externally adjustable guide vanes at the outlet to each coal pipe. These guide vanes are designed and positioned to either capture or divert the pulverized coal from entering the outlet. Field experience has demonstrated that ...
