### SteelBillets bars and rods Britannica

SteelSteelBillets bars and rods Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster they are rolled from blooms by billet mills. One method of rolling billets which are usually 75 to 125 millimetres square is to use a three-high mill with box passes as shown in A in the figure. When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the

### Autogenous and Semi-Autogenous MillsScienceDirect

In recent times these mills have successfully replaced the conventional rod mill–ball mill configurations. In Australia the number of AG/SAG mills increased from about six in 1984 to more than 40 in the following 5-year period . The number of installations worldwide by mid 1989 was about 471 and presently the number is growing. The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM" a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch") a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the

### Mill (grinding)Wikipedia

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. AG 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 done by a ball mill. AG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult if not impossible.
