The Bond ball and rod mill tests are used to determine specific energy consumption (kWh/t) to grind from a given feed 80% passing size (F80) to 80% passing size product (P80). Variations in the original Bond methodology are used to account for the effect of feed size distribution when feed to the ball mill is coming from

A bar and rod mill, also known as a rolling mill, is a facility used for the production of metal bars and rods through a process called rolling.It is commonly used in the metalworking industry to shape and form metal into various profiles and sizes. The primary function of a bar and rod mill is to reduce the cross-sectional area of a metal …
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). Grinding action is by line contact between the rods …
Typically this type of mill can deliver a product with a fineness of less than 0.1 mm. Testing of material is needed before hand to determine the suitability of the ore for processing in an autogenous mill. 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 bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
Rod Mills are similar with the Ball Mills xcept 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.

Salient Features. To prevent the conditions leading to rod charge tangling, the length-to-diameter ratio is maintained at 1.4 to 1.6. Use less steel than a ball mill because of the lower speed and better contact between the media and ore.
Double wire rod block mill comprises bevel-type gear in gearbox that is made of superior grade forged steel. Parameter: Mill form: Cantilever roller ring rolling mill. Annual Capacity: 50,000 up to 500,000 tons. Raw Material: From 60*60 up to 200*200 billets
These rods are made of steel and are about the same length as the mill. The rods are placed in the mill with the length parallel to the axis of the cylindrical shell. As the mill rotates, the rods tumble and break up the material that is fed into the mill. Applications of Rod Mill. Rod mills are used in a wide range of industries, including:
The diameter of the hollow shaft at the discharge end of the rod mill is larger, and there are mainly overflow-type rod mills and open-type rod mills. 3. Different grinding media. Ball mill. Ball ...
High-speed 5.5-16 mm wire rod and rebar in coil mill in operation at Silat, featuring new patented laying head technology.
The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.
Mill liner. A "Bond" rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of six laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner. Work
Further fast change-over is the key to the flexibility of the mill. The mill is to be able to convert to the next order while still processing the current one and change the line from one product to another with virtually no downtime.
