Abstract 

The object of the research to develop an analytical method for determining the armor wear rate of the drum ball mill was the boiler TP-100 (TP-100A) of the 200 MW power unit of Burshtyn TPP (Ukraine), equipped with two individual dust-preparation systems with drum ball mills KBM 370/850 (Sh -50A).

An effective analytical method for determining one of the main performance indicators of a drum ball mill – the wear rate of the drum armor, grinding balls and the relationship between them in case of “G” grade coal combustion for TP100 boilers is proposed. Its essence is to reduce human labor costs, more accurately determine the wear rate of the drum armor and grinding balls. This method is characterized by the fact that the main estimation indicator is the drum armor wear rate depending on the manufacture quality of armored plates (manufacturer).
