Sep 09, 2020 Moreover, the diameter of the hollow shaft of Rod mill is larger than that of ball mill of the same specification. 3. Different grinding medium. The Rod mill usually uses the steel rod with a diameter of 50-100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium.
The power needed to operate a rod mill could exceed 30 of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by bar mills and this is for comparable performance.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency 5
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 Critical Speed is used for the determination of ball mill
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
ball mill section. As an example, Table 1 presents AGSAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi, the calculated figures would suggest that the AGSAG mill is very inefficient, while the ball mill is significantly more efficient than Bond would predict. Figure 1
Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
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.
