coal grinding mill used

There are several methods to estimate the grindability of coals. One of the most commonly used methods is the Hardgrove Grindability Index (HGI). HGI for coal is determined by grinding 50 g of sample in a ball and ring type mill for 60 revolutions, after which the product is sieved through a 200 mesh sieve (75 micron screen) (Speight, 1994). HGI is computed by measuring the undersize of the product.

Mill Comparisons—General The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained.

The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring). Coal Pulverizer Inlets and Outlets. Louvres (nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal is transported pneumatically.

Drum mills. The drum mills are used for fine and ultra-fine grinding of brittle materials. Discontinuous operated drum mills make, in addition to size reduction, homogenization of the material to be ground possible. Drum mills have a horizontal grinding drum rotating around a fixed center of rotation.
