A Comparison of Three Types of Coal Pulverizers

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.

What are the types of coal? U.S. Geological Survey USGS.gov

There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, 3.0 Intending bidder must have experience of having successfully executed supply of vertical type coal pulveriser / grinding elements for coal mills during last seven (7) years prior to the date of techno- commercial bid opening with either of the following: a) One order costing not less than Rs. 579.46 lakhs.Technical specification for Procurement of Wear Parts
