Spiral separators can therefore be used to take out the coarser iron oxide grains in the primary grinding circuit to save grinding energy and help achieve a higher iron recovery. Figure presents a typical flow sheet for processing an oxidized ore containing about 30% Fe using a combination of spiral and SLon magnetite separators and reverse flotation.

Grinding also increases the total surface area of a given weight of feed, thereby allowing more space for steam condensation during the conditioning process. This results in a higher feed temperature and more water absorption which together, within the time available, increases gelatinization of raw starch.

Milling and grinding aren''t the same, however. They each work in a different way to remove material from a workpiece. What Is Milling? Milling is a machining process that involves the use of a milling machine to remove material from a workpiece. Milling machines feature cutting blades that rotate while they press against the workpiece.

The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
