Feed size should generally be -18, for ball mill and -12 for rod mill. They are of a sturdy, rugged design to handle frequent use with hard materials. The batch ball and rod mills require a drive roll to rotate the mills. The batch ball mill should be run between 56 RPM and 70 RPM. The batch rod mill should be run between 47 RPM and 79 RPM.
3.2 Rod Mill Design A different approach is taken with the rod mill design where equations by Bond and Rowling are used to calculate the mill power draw. The Morg rdshammar equation and the IMM equations are shown for comparison. The method of use is similar to the AM section 3.3 Ball Mill Design
Steel Ball Mills amp Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s.

A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. Conventional rod mills are either high or law discharge. In the high discharge mill, the discharge trunnion. is. the same size or only slightly
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm 2 in. and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh.

Prominer provides ball mill rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries. It can carry out dry or wet pulverizing and can meet demand for sustainable large-scale production.
Apr 07, 2016 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 ...
Since for the ball mill design we are using 80 passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as 3 2.44 0.2 3 However, it is important to note that C3 0.914 vessel used in producing the ball mill was got from a

Common examples are rod and ball mills, both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action. Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis.
