acts as a grinding aid and helps stabilise the grinding bed in the mill. However, it also presents the risk of pre-hydration. This is where the use of vertical mills for slag grinding offers a further benefit as the mill not only grinds the material but also dries it in the process. The normally-moist slag, with an eight per cent water content,
