The main characteristics are: Lower investment costs than other types. Smaller capacity for each mill means a better degree of combustion flexibility. They require periodic roller changes as they wear out during pulverizing, increasing the maintenance cost.
Failure analysis of coal pulverizer mill shaft - ScienceDirect
2003. 12. 1.· Failure of a ball and race type coal pulverizer mill shaft has been analysed. It was found that the shaft, made of EN 25 steel, failed by fatigue. The fatigue cracks originated from the keyway area, unusually from the top edge. The presence of elongated manganese sulphide inclusions due to improper heat treatment had reduced the ductility and CVN toughness of the material, and thus made the,Pulverizer / Mill Upgrades - Babcock,Pulverizer / Mill Upgrades.
