Rod mills create a coarser product than do ball mills and typically operate at a slower mill speed. Rod mills can be either wet or dry designs. Strommashina Corp. rod mills are designed for wet grinding of various ore and nonmetallic minerals as well as construction materials of medium hardness. These rugged highly efficient rod mills offer ...
Rod mill grinding rods of all sizes and length. High hardness, range is 45~55HRC Low bending, less than /m Dense microstructure, Bainite +Pearlite+Carbide Low breakage rate, more than 15000 times/ Low unit consumption, 40% reduction compared to unprocessed round steel
Applications The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/ coke, and other materials for both wet and dry applications.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon 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]

XMB series rod ball mill is an efficient laboratory grinding equipment for wet grinding of ore or other materials. Steel balls can be used as grinding medium instead of steel rods. GTEK LABORATORY, China''s best laboratory minging equipment supplier.
112016· The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length. Based on these observations and working on wet overflow mills, Rowland and Kjos [2] suggested that the power draw at the pinion shaft per unit mass of rods is given by () P M M R = D − J R ϕ C where P M / M ...
rod mill for mineral ore grinding_Rod mills, how they function Mine 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, sim
The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct.
SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through automatic operation ''s process engineers will assist you in creating an efficient softwaredriven process, from circuit design to startup and optimization, to ensure you get your desired grinding results.
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. To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at to

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.
AG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. AG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible.
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 to Rod mills accept feed up to about 50 mm ...
Peripheral Discharge Rod Mill can be easily maintained at peak operating efficiency by the periodical addition of rods. CPD Rod Mills give a wide range of flexibility to sand plant operation. By changing the rate of feed, pulp dilution (wet grinding), and discharge port area it .

Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding, primarily by attrition, Rod Mills require comparatively low levels of power to operate. Rod Mills can be either wet or dry designs. Once replaced by AG and SAG mills, Rod Mills have had a .
Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.
