This requisite temperature control is accomplished by mixing cold air with the hot or primary air delivered to the mill.
Today's coal-fired utility boiler operation needs pulverizer designs to supply pulverized coal with required throughput and coal fineness, and also perform with lower specific power consumption, especially at reduced mill load. The designs must be capable of proper mill operation and control with.The four most common types of coal pulverizers are Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.
