What are the different types of coal?
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 …

grinding process in coal
Coal grinding is preparatory process to a creating mixture for combustion in boilers at thermal power plants. To a high-quality fuel creation for the TPP units furnaces (fuel has the coal basis), needs to achieve the maximum material grinding degree and maximally reduce the coal dust moisture content.

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. The speed
