Milling Plant. In suction milling, the exhauster fan is located between the mill and the boiler. It pulls the hot air from theoutlet 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.
The recent interest in coal energy has led here to a method for collecting gaseous samples when coal is ground to a fine powder by Bleuler volumetric milling. A knowledge and understanding of the composition of the gases thus formed from grinding freshly mined coal may be applied widely in coal-gasification and other studies.

A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.
