[0002] Slag powder, short for granulated blast furnace slag powder, is a high-quality concrete admixture. It is dried and ground to a powder with a high fineness and activity index. The water-quenched blast furnace slag grinding unit is an auxiliary device used for grinding water-quenched blast furnace slag powder and is widely used in the field of slag powder processing technology.

[0003] The existing patent application number CN 202221261093.X discloses a water-quenched blast furnace slag grinding device.
