The reason why rod mill is called rod mill is that its grinding medium is steel rod, while the grinding medium of ball grinding mill is steel ball. Because the shape of the grinding media is different, the working mode has its own characteristics. When the steel rod is in motion, the gap between the rods is a regular long strip, which plays a ...
