Groundwater and other extraneous moisture is known as adventitious moisture and is readily evaporated. Moisture held within the coal itself is known as inherent moisture and is analysed quantitatively. Moisture may occur in four possible forms within coal:

  • coal pulverizer used

    Coal Pulverizer Purpose. Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose. Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, thisLaboratory Sample Pulverizers 911Metallurgist,Pulverizer performance is not appreciably affected by moisture content or size until the proportion of dried, smaller-size fraction is somewhat greater than 35 percent.
