The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit or as fine as 35 mesh operating in closed circuit with a screen or other sizing device. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained by restricting ore feed size to 3/4".
