Effect of Grinding Rod Media Load on Rod Mill Performance Effect on Rod Mill Power Draw. The general relationship between mill power draw and charge level is as shown in Figure 2. As previously discussed, the exact shape of this curve, and the position of the peak, may vary slightly for each particular mill
Rod mills are very similar to ball mills, except they use long rods for grinding media. 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.
A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. Rod mills came into use in the United States beginning in 1900s and
Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. Ball mill exterior, interior, and grinding media
perhitungan peripical speed grinding mill. Rod mills are very similar to ball mills, except they use long rods for grinding media. 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
mill charge-steel rods − 6 × 38.1 mm dia × 0.53 m long steel rods plus. 2 × 44.5 mm dia × 0.53 m long steel rods. Control of the grinding media charge can be made by continuous monitoring of the mill power consumption. A fall in power consumption to a certain level necessitates charging of fresh grinding media. Continuous power

Jan 01, 2016· The rod mill feeds a wet ball mill at a feed size of 1.0 mm (1000 μm) and produces a product with 80% passing a 150 μm screen. The rod mill is in an open grinding circuit. Determine: 1. the shaft power of the rod mill, 2. the size of the industrial mill. Data: Laboratory Standard Bond Test: Rod Mill: Grindability index at 10 mesh = 13.5 kWh/t
Rod Mill Grinding Rods 911Metallurgist. Most operations report that grinding rods are added to the mill two or three times a week. Depending on the media consumption rate, this could cause a wide fluctuation in mill power draw, and operation at least part of the time near the peak of the power versus charge volume curve.
Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line. Approximately 30-40% of the ball charge will be void space.
Rod mills, except they use long rods for grinding media. 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.
Mill steel charge volume calculation we can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media while the grinding media sorting is performed when the ball l.
Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput.
Grinding Rod, Steel Rods, Grinding Media manufacturer supplier in China, offering Supply Good Quality Grinding Media Steel Rod for Rod Mill in Metal Mine, Good Wear Rate High Chrome Casting Grinding Media Steel Ball Used in Ball Mill, Dia. 1"-5" High Chrome Casting Grinding Media Steel Balls Used in Ball Mill and so on.
Less void spaces exist in a rod charge tan in a ball charge. Therefore, these is more grinding contact between metal an ore per surface are of media in a rod mill. Lower steel consumption per ton of product occurs in a rod mill than in a ball mill due to better contact between steel and ore. The action within the rod mill causes the energy of
The batch ball and rod mills require a drive roll to rotate the mill the proper grinding speed, usually 60%- 75% of the critical speed for ball mills and 50% to 90% of critical speed for rod mills. TECHNICAL SPECIFICATIONS (8″) PRODUCT INFO SHEET PDF

Article Factors affecting the production output of rod mill- Grinding Media. Rod mill is a kind of mill whose grinding body is steel rod. Generally, the rod mill is of wet overflow type, which can be used as the first-class open circuit grinding, and Factors affecting the production output of rod mill- Grinding.
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
