DetailsThe % fines in the rod mill feed. For the purposes of rod mill performance analysis, "fines" can be arbitrarily defined as particles finer than 75 microns (200 mesh). Rod mill feeds which contain less than approximately 10% fines are good candidates for fines addition testwork. The % solids by volume of the rod mill discharge.
DetailsThe input material for these mills is normally billet. A billet mill can be combined with the long product rolling mill through a roller hearth furnace in case the available input material is bloom. Similarly on the finishing mill side the mill can be combined with a wire rod mill so that wire rods can also be produced from the mill.
DetailsA rod mill is typically more efficient within a drum diameter range of 5 mm to 0.4 mm (4 mesh to 35 mesh). This makes it more suitable for applications where larger particles need to be ground, considering the mill diameter. ... In contrast, we find rod mills more suitable for tasks like preparing feed for gravimetric ore dressing methods and ...
