Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded.

Next, you'll need to measure the width and depth of the channel. Using a blunt, slender tool (such as a flat head screwdriver), carefully and gently pry that section of the old seal out of the channel. You just need to pull out enough to configure the width of the channel with a ruler or tape measure (figure on approximately 2 inches of gasket).

Pulverized coal, which has the consistency of face powder, is made from the relatively abundant lower grades of coal and blown into the blast furnace. Granular coal, similar in size to sugar, is also being tested in blast furnaces. At the beginning of 1994, 31 coke plants were in operation, less than half the number a decade earlier.
