GET QUOTATION. Rod mill is a commonly used grinding machine, which is named after the steel rod (grinding media) loaded in the cylinder.
As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.
It is because of Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. Helen Jiang
Ball Mill & Rod Mill Design. In all ore dressing and milling processes, including flotation, cyanidation, gravity concentration, and amalgamation, it is necessary to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw ...
Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3. In wet grinding, the solids …
Fodamon engineers share the differences between ball mill and rod mill as follows: 1. Appearance and structure The shape ratio of the barrels of the two mills is different. The ratio of the length and diameter of the rod mill barrel is generally 1.5-2, and the inner surface of the liner on the end cover is a vertical plane. There are various ...
Rod Mills Over Ball Mills. May 08, 2020 Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31, saved energy by 27, and reduced the consumption of grinding media by 47.
Five differences between ball mill and rod mill 1. Different ways of discharging ore The ball mill has two discharge methods: overflow type and grid type. The grid type has a lower slurry level, which makes it easier to discharge qualified minerals in time, but the grid plate is easy to block and maintenance is not very convenient.
Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is -4 to 35 mesh. Rod mill produced by Fote Application fields of rod mill Applications of rod 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.
The grinding medium of the ball mill is steel balls with a diameter of less than 100mm; while the rod mill usually uses a steel rod with a length of more than 500mm as the grinding medium. 4. Different filling rates of grinding media. The filling rate of the grinding medium refers to the percentage of the grinding medium in the grinding volume.
Dec 30, 2019· 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 ...
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 rods to be directed to the largest sized …

The grinding fineness of the ball mill is finer, usually the output particle size is between 0.074-0.4mm, while the output fineness of the rod mill is between 0.833-0.147mm. 4.Classification is different. Ball mills can be divided into overflow-type and lattice-type ball mills, while rod mills are classified into overflow-type and open-type rod ...
milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is. Contact
