Pulverizer Capacity is not simply "tons throughput per hour!"

the fineness is reduced from about 75% passing 200 mesh to 45% passing 200 mesh, as much as 30% more coal throughput can be pushed through the pulverizers. The previous example is often inadvertently done by increasing primary airflows or opening classifier blades up to increase the coal flow to the furnace by sacing coal fineness.
