Slag is a common raw materials for cement industry. The hardness of slag is around 6-7 in Moh’s scale (harder than cement clinker).

For the aim to grind slag (15-20 mm) to a final fineness of 30 microns.  After the slag dry,  the slag less than 50mm fed into the rolling mill, the slag will be grinded to  be powder by squeezing crushing strength by the roller.

adopting the rolling mill for slag grinding,  it has very low power consumption, and the wear parts will be long time. And high capacity. It can replace several crushing stage. The hydraulic system supply 250 Mpa pressure. During the working, change the pressure to change the finished produce size.
