### 7 Differences Between Ball Mill and Rod MillXinhai

3. Grinding medium of ball mill and rod mill. The rod mill usually adopts the steel bar with a diameter of 50-100mm as the grinding medium while the ball mill often uses steel ball as the grinding medium. The difference on grinding medium is the main difference between the ball mill and rod mill. Ball Mills vs Rod Mills. Because of this the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft.

### Technical Performance and Application of Ball Mill and Rod

Rod mill. Unlike the ball mill the grinding medium in the rod mill is a steel rod so the working characteristics are significantly different from those of the ball mill. Since the steel balls are in point contact the steel rods are in line contact. When the steel rods are sandwiched between the steel rods the coarse particles are first As such when the product is sticky rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30 of the power used in a ball mill.
