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 speed

What are the types of coal? - USGS

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 ...

What are the different types of coal? American ...

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.
