The four most common types of coal pulverizers are 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
Coal mill hot air inlet temperatures should never be more than 600 F and the outlet temperature should not exceed 200F on Raymond coal mills If the flow of raw coal to the coal mill is interrupted for any reason (for example plugging failure of the coal feeder etc ) the outlet temperature of the coal mill can quickly climb to dangerous levels
With adequate mill grinding capacity a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99 5% or higher 50 mesh and 80% or higher 200 mesh while one equipped with a dynamic classifier produces coal fineness levels of 100 mesh and 95% 200 mesh
Jan 12 2019Bituminous coal Bituminous coal contains 80% of carbon It is the common coal It is compact and black On burning it produces more heat than peat and lignite Its calorific value is 30 to 35 kJ/g Anthracite coal It contains 90% of carbon It is
Most existing pulverizers—both the vertical-shaft and ball-mill types—come with a static classifier Its blades reject coarse particles to produce a stream of coal particles that are mostly about 0 0029 inches (74 microns) across Obviously not all of the particles leaving the pulverizer are that size
