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]
DetailsTherefore, the Rod Mill causes no excessive grinding, enabling you to produce products of relatively sharp particle size distribution curve. Features. The Rod Mill is a grinding mill used for coarse grinding or fine grinding, which offers the following types and uses. 1) Peripheral Discharge Type. 1. Wet grinding type (E.P.D. type and C.P.D. type)
DetailsThis is due to the fact that the diameters are measured inside the liners, while other mills measure their diameter inside the shell. Rod Mill Capacity and Sizing Table 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.

DetailsWith this modernization, Zenith aims to widen its portfolio to include round bars and maximize the rolling speed for smaller-diameter products. Currently, the wire rod mill produces 780,000 tons per year of wire rod from 11.5 up to 26.5 millimeters in diameter in commercial steel grades.
DetailsA survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.
DetailsThe rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining the rod mill work index ...
DetailsAs the length to diameter ratio of the mill should be in the range of 1,2-1,5, the biggest rod mill will convert maximum 1500 kW. Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials).
Details1.27 for the rod mill and 0.67 for the ball mill. The particle size distributions reported are shown in Figure 1. It follows that the No 1 rod mill/ball mill circuit was operating very effi ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices.
Details1.GMBZ series energy efficient rod mill is based on domestic traditional rod mill technology, it is new energy-efficient products after structure optimized. This series of rod mill adopt high-end roller bearing instead of the traditional bearing support with the feature of small running resistance, and the energy saving is 10 to 20%, production ...
DetailsInternal diameter of a wire rod coil usually varies in the range of 810 mm to 910 mm depending on the mill equipment. The external diameter of the wire rod coil will depend on its weight and will be in the range of 1100 mm to 1300 mm. The coil weight can vary from mill to mill in the range of 600 kg to 2.5 tons.
DetailsThe mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG 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 of a ball mill.
Detailsthe apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where …

DetailsThe invention relates to a method for determining the rod diameter of a rod mill, belonging to the field of ore grinding and levigating technology. The method provided by the invention comprises the following concrete steps: (1) measuring the uniaxial compressive strength alpha of the ore to be milled, as a mechanical basis for determining the accurate rod diameter; (2) performing …
DetailsAttrition mill : IN this case, the charge is ground to fine size by the action of a vertical shaft with side arms attached to it. The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the

Details1 The rod mill usually uses a steel rod with a diameter of 50-100 mm as a grinding medium. The length of the steel rod is 25-50 mm shorter than that of the cylinder, and is usually made of high carbon steel containing 0.8%-1% carbon. 2 The loading amount of the rod is about 35%-45% of the effective volume of the rod mill.

Detailsapplications. Threaded rod is often used along with a nut and/or square plate washer when embedded in concrete to achieve required pull-out values. The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4" through 4" diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar.
DetailsThe 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).
DetailsA 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).
