Abstract: A grinding system includes a mill housing. A milling unit in the housing has a moveable milling member operable to grind coal. A drive system includes a drive shaft and at least one gear in a gear case drivingly connecting the milling member to the drive shaft. An exhauster is operable to draw air into the housing through an inlet and draw a mixture of air and powdered coal out of the housing through an outlet. A pressurization system is operable to maintain the gear case pressure at a higher pressure than an air pressure in the housing. In one method of grinding coal a gear case pressure is maintained at a pressure higher than a pressure at the housing inlet while the milling member grinds coal into a powder and the exhauster draws a mixture of powdered coal and air out of the housing.
