The efficiency of screening is a function of the moisture content of the coal. If the coal is completely dry, screening works well although dust will be a problem. As the moisture content of the coal increases, the efficiency drops off sharply and reaches a low point at moisture contents of about 15 to 20% due to screen blinding. Increasing
