As described earlier, it is a high-speed mill that pulverizes coal by the combination of crushing, attrition and impact. The BTM System should be equipped with a crusher/ dryer for high moisture coals, or coals with a top size greater than 3/4 inches. The primary crushing and drying is performed in the crusher/ dryer.

Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
