During the conveying process, the material can be turned over evenly on the stable moving plate, small powder flying, which could reduce oil loss and air pollution. Oilseed drying machine has a high degree of automation, and the steam amount can be rapidly and continuously adjusted according to the moisture content of the raw material.
In general, the moisture content increases with decreasing rank and ranges from 1 to 40 percent for the various ranks of coal. The presence of moisture is an important factor in both the storage and the utilization of coals, as it adds unnecessary weight during transportation, reduces the calorific value, and poses some handling problems.
The heat content of anthracite ranges from 26 to 33 MJ/kg (22 to 28 million Btu/short ton) on a moist, mineralmatterfree basis. The heat content of anthracite coal consumed in the United States averages 29 MJ/kg (25 million Btu/ton), on the asreceived basis (, containing both inherent moisture .

Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.
