Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. […] Laboratory ...
Get PriceBall-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel- Head Ball-Rod Mill, as this unit can carry a …
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.
Rod mill. Unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill. Since the steel balls are in point contact, the steel rods are in line contact.
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.
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 batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
Introduction. The rod mill is loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customer’s needs.

Rod MillIntroduction The HongxingRod Millmanufacturer adopts advanced controllable feeding and discharging technology, combined with the actual grinding material, with the appropriate grinding body, and the traditional surface contact is changed into line contact so that the discharge granularity is more uniform and the output is higher.
Introduction. Therod millis loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customer’s needs.

Rodmills are very similar toballmills, except they use long rods for grinding media. The rods grind the ore by tumbling within the themill, similar to the grinding balls in aball mill. To prevent the conditions leading torodcharge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
In theball mill, commonly used have the latticeball milland overflowball mill(named from different drainage structure), and therod milldoes not use the grid plate drainore, only overflow type and opening type two kinds, the diameter of the hollow shaft at the drainage and end is generally larger than the same specificationball mill.
Thus, quantitatively, less material can progress through the voids in therod millgrinding media than in theball mill, and the path of the material is more confined.

Multiple stages may include arod millfollowed by aball mill(two stage circuit), or a semi-autogenous grinding (SAG)millfollowed by aball mill(two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. If aball milluses little or no water during grinding, it is a ‘dry’mill.
Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as forball mill. The size of feed particles to arod millis coarser than for aball mill. The usual feed size ranges from 6 to 25 mm.
Grind coarse feed material with a reliableRod Millthat won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions likeRodMills.RodMills are particularly useful, if you run a low tonnage operation and are looking for coarse product.
Rodmills are less common thanballmills for grinding minerals. The rods used in themill, 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.
Therod millis generally more efficient than theball milldue 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.
Arod millfeed conveyor (4) accepts all of the ore from these feeder belts for ultimate transfer to therod mill. This conveyor is normally equipped with a weightometer (5) to monitor the flow rate of ore to therod milland ultimately to allow control of this flow.
Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in arod mill,ball millor pebblemill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, arod mill, and some or all of the work of aball mill.
