It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical. what water does is kind of provide a mode of
rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill.
