In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
Secondary bars are usually re-rolled in a locally made rolling mill. Thus giving it inconsistent properties. Primary bars are made from world-class technology on a high-speed fully automated mill with horizontal and vertical stands. Rib pattern. The ribs in secondary steel are done using the local rib cutting process done by hand tools.
