For final utilization and for treatment by some of the newer beneficiation techniques, the top size of the coal is often further reduces. Then the coal undergoes pulverization which reduces the top size to 1/8'' and/or grinding which reduces the top size to 1 mm or less. This handbook examines the intermediate and fine grinding of coal.
