is the pulverizer capacity influenced by moisure
It is generally considered that for a desired coal fineness and selected feed size the mill capacity has a direct relationship with grindability however this capacity is significantly influenced by the moisture content of the coal as is evident from Figure 42 8 If the coaldrying operation is inadequate the mill capacity is dictated by moisture content and not by grinding
Pulverizer capacity is affected by mechanical variables within the pulverizer as well as the properties of coal and operational controllable variables Typical pulverizer capacity limitations are indied by the following variables Achieving Optimum Pulverizer Performance Innovative moisture in the coal
