what are the differences between ball mill and rod mill

Though there is no sieve plate, the discharge pipe is cast with reverse threads, which makes that the large ores and balls are hard to discharge from the ball mill machine. Overflow discharge ball mill can grind ores into the size under 0.2 mm, so it is very suitable for the second grinding system. The capacity of it is about 15% lower than grate discharge ball mill in the same specification, and the loaded grinding …
