A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to 120 m/sec).
Particle size reduction, screening and size analysis Objective ... Ball, pebble and rod mills are rotating cylinders that are partially filled with metal or ceramic balls, flint pebbles or rods. The units are capable of producing very fine powders, such as nano sized .
Stock materials come as plates (for CNC milling) or rods (for CNC turning) in a variety of sizes. In the tables below we summarize the most common blank dimensions found in a typical machine shop. Note: 0.3 mm to 1.5 mm of material will be removed from each side of the blank during machining (that is up to 3 mm total).
Grinding medium of rod mill The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials: A High carbon steel
Outline of Free Size Rolling for Hikari Wire Rod and Bar Mill metry during roll gap change is small. In addition, as shown in Fig. 4, the spread ratio of steel material in the 3-roll method is smaller than that in the 2-roll method. Because of these characteristics, the
As a rule, wire rod mills are designed for an annual output of between 300,000 t and over 800,000 t (two strand mills). The mills are capable of rolling at speeds ranging from 50 meters per second ...

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 mill grinding medium is steel bars.Rod mill can make discharging size more uniform, and make output higher. In some cases, rod mill can perform crushing instead of short head cone crusher.
The grinding medium of rod mill is steel rod which is recognized that the length of rod is less than 7m because the large length is easy to twine. The diameter of rod is 75~150mm. Grinding rod should have enough stiffness and hardness to keep straight, and it should not be too crisp which causes the rod broke into pieces without enough wear.
Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.
4.2 to 5.2 mmφ. With our in-house developed 4-roll mill in Kurashiki and 3-roll mill in Sendai, we can manufacture mid-size steel bars with high dimensional accuracy and wire rods with a 0.1-mm pitch. A wide range of size variations We have various types of non-destructive inspection equipment for everything from billets to products.
Therefore, it has advantages of even discharging size and high capacity. Rod Mill Structure: The rod mill is composed by the cylinder part, feeding part, discharging part, main bearing part and driving part, which is similar with the other mills. Our Advantages: 1. The discharging granularity of rod mill is evener and the output is higher. 2.
The rod mill In the rod mill, high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls. This mill gives a very uniform fine product and power consumption is low, although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size.
The effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.
Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the
The basic difference between drawing of rod and wire drawing is the size of the starting material which is processed. Bar drawing is the term used for drawing of rods from the steel rounds, while wire drawing applies to drawing of wires from steel wire rods. Wire sizes down to 0.03 mm are possible in wire drawing.

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 …
Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod charge by volume.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, 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 [5]
For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill efficiency factor.

In standard rod-milling it will be found that rods spread apart at the feed end in the amount of the maximum size of feed entering the mill. In the center peripheral discharge mill the rods are spread at both ends and parallel throughout the length of the mill.
In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks.
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).
ROD MILLS Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill
