Ball and Race Mill - Me Mechanical
Fig 1: Ball and Race Mill. The air fed to the ball mill is heated in the air heater. In the separator dust (finely pulverized coal) is separated from large coal particles which are returned to the ball mill for regrinding. The dust moves to the cyclone. Most of the dust from cyclone sent to bunker.

Mill (grinding) - Wikipedia
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
