Milling Plant Газогенераторы МСД

Milling Plant. In suction milling, the exhauster fan is located between the mill and the boiler. It pulls the hot air from the AH outlet through the mill and picks up the ground coal from the mill to deliver the mixture to the burners. Hot air is suitably mixed with ambient air to meet the mill outlet temperature require­ment.
