Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3 ), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the ...
From the hopper, the slag is conveyed to the top of a 100t/hr Loesche vertical roller mill, with a 4.6m table diameter and a 3.1MW drive. It has two main rollers and two auxiliary rollers. I would say that it is the best available technology for slag grinding.

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]. Of the 16.3 Mta of steelworks slag in Europe, 52.3 % are BOF slag, 34.9 % are EAF slag and …
Gebr. Pfeiffer said the mill will grind slag and cement to a fineness of between 3000 and 3800 blaine at a rate of between 235t/hr and 340t/hr. It says the mill improves plant availability by the active redundancy of the grinding rollers, enabling mill operation with reduced rollers in the event of maintenance work or a malfunction.
Carlos Thomas, ... Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.
This study aims to model grinding of a Polish ferronickel slag and evaluate the particle size distributions (PSDs) of the products obtained after different grinding times. Then, selected products were alkali activated in order to investigate the effect of particle size …

grind fine to very fine products in a dry process. The machine's first market was the cement industry where fine grinding is required for both raw meal mix and ce - ment powders (from a hundred microns to a few microns achieved with our TSV air classifier). In the meantime, the calcium carbon-ates and steel slag grinding markets found
For the steamed concrete, the fineness of slag grinding effect was also studied as 2900 and 6380 cm 2 /g as well as the w/c ratio as 0.40 and 0.50. The obtained results proved that the treated ...

PSC. PSC or Portland Slag cement is manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement by means of mechanical blenders. Normal composition of portland cement is 30 % clinker, 5 % gypsum and 70 % blast furnace granulated slag.
