In fact, to combat this fire hazard, arrangements for mill-inerting systems with inert gases (e.g., N 2 and CO 2) need to be made (another purpose is to reduce air supply). This is more important for ball-and-tube mills, especially when these are operated with one side only. Therefore, CAD comes into operation whenever there is need to bring down the mill temperature. Naturally when this ...
