Li et al. [16] studied the use of wet-grind ultrafine blast furnace slag as a substitute for cement. The ball mill had a solid-to-liquid ratio of 2000 g/L, and a materials-ball mass ratio of 0.25. The mean size of the slag particles decreased from 18 μm to 2.3 μm after 1 h of grinding.
Grinding is usually used to increase the specific surface area of steel slag to improve its activity. However, due to the large amount of hard-to-grind minerals in steel slag, a large amount of energy is wasted in the grinding process. Therefore, the current investigation aims to remove the hard-to-grind minerals in steel slag as much as …

3. Experimental work3.1. Bond grindability tests. The ball mill grindability tests were conducted in a standard Bond mill for 90-μm test sieve. As received, the slag was finer and hence the clinker was also reduced down to similar fineness by crushing in a roll crusher and −3.36 mm samples were used as feed materials for the tests.
The available capacities are from 500 tons to 3,000 tons per day. A vertical roller mill combines intermediate crushing, grinding, drying, separating & conveying processes. While grinding the slag, the fineness will be as per Blaine > 4,200 cm2/gram. The initial moisture of 15% in the slag will be reduced to 0.5% in the process.
