Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media. This also results in lower steel consumption.

Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills.

A Rod Mill has for Working Principle its inside filled grinding media, in this case STEEL RODS. These rods run the length of the machine, which is most commonly between eight and sixteen feet in length. The diameter of these rods will range from, when new, between two and four inches. The rods are free inside the mill.

Tubular Rod Mills Sciencedirect. Jan 01, 2016 As the considerations of rod mills are similar to the ball mills, some of the problems given below require the use of formulae described for ball mill operations in Chapter 7. 8.1 The inner dimensions of a rod mill were 1.8 1.8 m and the largest diameter of rod charged was 76 mm.

The same principle applies to drill rods. With proper use and handling in the field, drill rods will last longer, give you better results and ultimately lead to lower operational costs. Consider that rods typically make up 3 percent of total drilling costs. But if a rod fails prematurely or unexpectedly, it can mean a significant jump in those ...

Problem In Rods In Rod Mill. Applications of rod mill,the types of rod mill discharge trunnions are overflow perforated overflow return spiral grate and peripheral thus the engineer can fit any one of fifteen variations of sizes and type of discharging a rod mill into the problem on which he is working the superiority of the steel head rod mill is due to the allsteel construction.

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 Dimensions. Rod tangling is a problem that should be avoided by using straight rods. Rods < 6 meters are generally never straight. Rods should be 152mm shorter than mill length.

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).
