Ball mills work well for finer grinding, whereas rod mills can handle coarse grinding. Both of them use a grinding medium in the form of rods or balls and rotate the shell. In most cases in mineral processing applications, the grounded particles flow in the form of a slurry to the concentration process.

Usually, the charge ratio of the ball mill is 40-50%, and that of rod mill is 35-45%. Ball mill VS rod mill-processing property. The ball mill machine has the high grinding production capacity and strong adaptability to materials. The fineness of the ground product is high, and the output size is fine.
