The grinding of clinker and cement and of granulated blast furnace slag and slag in vertical air-swept grinding mills dates back to Ernst Curt Loesche's invention. In 1927, he applied for a patent for the world's first spring-loaded air-swept mill – the beginning of the triumph that is Loesche vertical roller mills.

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 ).
