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 ...

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when intergrinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.

Comminution theory focusses on the relationship between energy input and the particle size produced from a given feed size. 2 The most common breakage methods are impact and attrition, mostly by ball mills. This compares with the compression mechanism, as well as attrition, utilised in both highpressure grinding rolls (HPGRs) and vertical roller mills (VRMs).
