The grinding plant for Anshan was designed for a grinding capacity of 90tph at a ground blast furnace slag product fineness of 4000cm 2 /g according to Blaine. However, following the market trend, the plant now produces 83tph of ground blast furnace slag with a fineness of 4300cm 2 /g (acc. to Blaine).
The mill grinds the slag to around 4300 - 4500g/cm 3 (Blaine). To dry the slag while grinding, we need hot air, which is present in the mill at around 200°C. This is supplied by a burner from Loesche. The fuel is predominantly blast furnace gas, a byproduct from the blast furnaces that is high in carbon monoxide (CO).
Basic oxygen furnace (BOF) slag is an industrial solid waste generated in the steelmaking process [ 4, 5 ]. It is rich in CaO, SiO 2, Al 2 O 3, Fe 2 O 3 in chemical compositions, and the mineral phases of steel slag are mainly composed of C 3 S, C 2 S, C 2 F, C 4 AF, and the solid solution of divalent metal oxides RO phase.

Slag cement is produced by finely grinding granulated blast furnace slag, a glassy by-product of iron production, and blending it with Portland cement to create a product that has a number of advantages over mixes containing Portland cement. Environmental and LEEDS Benefits.
Granulated blast furnace slag is primarily used in Europe for the production of Portland blast furnace cement. The necessary grinding of the slag to the finenesses required for cement is now mostly performed in vertical mills (Fig. 7), which achieve throughputs of over 100 t/h [2].
Granulated blast furnace slag (GBFS) is a by-product from iron and steel industry. It has been used as one of major replacement materials for Portland cement to produce concrete. It has considerable advantages in addition to the ecological and environmental benefits compared with ordinary Portland cement [ 1, 2 ].
For the design of a slag grinding plant the special properties of granulated blast furnace slag have to be considered. Granulated blast furnace slag is moist, abrasive, fine grained and difficult to grind. It also needs to be ground very finely.
A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge, by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge.
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process. The concept of M- and S-rollers was established in 1992, which is one of ...

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness.
Blast furnace slag (BFS) was one of the most important by-products of the steel manufacture. According to incomplete statistics, about 220 million tons slag were generated in China per year (Ren et al., 2018; Duan et al., 2015, 2018; Cheng et al., 2021). The total stack capacity of the slag reached a billion tons.
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.
