Figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the …

Unlike the angular shaped particles produced in a roller mill, the pulverizing action of the hammer mill results in particles that are more rounded. These smoother surfaces make it easier for the grains to be blended with other components of the feed.². So Many Hammer Mills. A hammer mill is essentially a steel box surrounding a rotor.
