Ball Mill vs Rod Mill How To Choose Ball Mill or Rod ...

The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume of rod mill.

Ball Mills vs Rod Mills

Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined.

7 Differences Between Ball Mill and Rod Mill - Xinhai

The ball mill is commonly divided into grid type ball mill and overflow type ball mill (named by the different discharging structure). The rod mill is divided into overflow type and open type rod mill, whose diameter of hollow shaft is generally larger than that of ball mill with the same specifications. 3.

Ball Mill VS Rod Mill-xinhai

For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need a lower rotate speed and has a lower power consumption.

Rod mills, how they function - Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod mills usually require greater operator attention. It is important
