A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The rod mill (Fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods. The rods are placed axially in the mill and are loose and free to move within the mill. The internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point.

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.

FENN drawing systems can be designed up to 230 ft. long (70.1 m) with 200,000 lb. pull (90,718.474 kg.). A wire or tube drawing machine can be integrated to work with other FENN equipment, such as a FENN Turks Head, for producing straight lengths of shaped rod or wire or FENN Swagers for pointing material. Typical Materials.

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

Measuring ore grindability in rod mills. The Bond Rod Mill Work Index is a measure of the resistance of the material to grinding in a rod mill. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory ...

TIE ROD MOUNT When using tie rods extended on the rod end, the best application is a tension load. For a thrust load application, the tie rods should be extended on the blind end of the cylinder. Tie rod mounts are suited for many applications, but it should be noted that they are not as rigid as flange mounted cylinders and often require

Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm.

Advantages of rod drawing are that drawing speeds are relatively high and high area reductions (approximately 45 percent for stainless steel) are possible. Disadvantages are that it is a two-person operation and it requires an additional drawing operation, such as a plug draw or sinking, to remove the spiral pattern. Plug Drawing.

It then goes at once through the looping rod-mill which delivers it as coiled rod varying from 3/16 to % inches diameter, and a hundred or more feet in length. These coils are sent to the wire mills and the remainder of the process of reducing them to the diameter of wire required is accomplished by drawing them cold through dies .
