Molten slag is carried outside and poured into a dump. Slag is a byproduct of smelting (pyrometallurgical) ores and recycled metals. Slag is mainly a mixture of metal oxides and silicon, it can be classified as ferrous (byproducts of processing iron and steel), ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous ...

The blast furnace slag has a uniform particle size, and only needs to be prescreened when controlling the grinding particle size. The wear of blast furnace slag on blast furnace slag ball mill mainly comes from iron and iron oxide. These two materials have large plasticity and are not easy to grind in the blast furnace slag ball mill, which ...

Blast furnace slag. Blast furnace slag (BFS) is a byproduct from iron production in blast furnaces, which are fed by a mixture of ironore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

3. Experimental Bond grindability tests. The ball mill grindability tests were conducted in a standard Bond mill for 90μm 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 − mm samples were used as feed materials for the tests.

Better product quality can be achieved as compared to the ball mill product due to the better options for separate grinding. For example, in additive cement production, the blast furnace slag has to be ground to Blaine values of 5,000 cm 2 /g. Water demand and setting times are similar to that of a ball mill cement under comparable conditions .

The converter steel slag cannot be widely used in building materials for its poor grindability. In this paper, the grinding characteristics of untreated and pretreated (, magnetic separation) steel slag were compared. Additionally, the grinding property of pretreated steel slag was also studied after adding grinding aids. The results show that the residues (, oversize substance) that ...

Mode 1: The drying and grinding steps are carried out separately. First, the materials are sent to the dryer for drying, and then the dried materials are sent to the ball mill to be ground into powder. Mode 2: Drying and grinding are carried out at the same time, the material is ground with a vertical micropowder mill, and hot air is blown ...

Abstract. Grindingrelated parameters of blast furnace slag cements (BFC), such as Bond grindability, specific rate of breakage and breakage distributions were determined employing separate and intergrinding modes. Strength tests were performed on mortar specimens made by BFC prepared by these modes of grinding to the same fineness.
