THE SLITTING PROCESS Many steel producers operate mills based on multi slit technology. The majority of those mills have a size range of 10 or 12 to 40 mm. In some appliions, 8 mm is also rolled. Depending on furnace capacity and product size, 4slit, 3slit and 2slit operation is used. Even if the design speed of the mills may be higher, these mills run at rolling speeds ranging in most ...

Rod mills came into use in the United States beginning in 1900s and eventually became recognized as efficient fine crushers. The 1st ever built rod mill (2 m in diameter by 4 m long) was to be installed at a mine where a coarser feed was required for shaking tables. Crushing rolls and rod mills were eventually used commonly to prepare feed to ...

Rod mills are similar to bar mills at the front end, but the finishing end is different. Rods have a smaller section ( to 15 millimetres in diameter) and are always coiled, while bars are normally shipped in cut length. The final rolling in rod mills often takes place in a closecoupled set of 10 pairs of small rolls (200 and 150 millimetres in diameter); these are all installed in a block ...

Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower ...
