The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag cement.

the granulated blastfurnace slag is partially dried in a rotary or in a vertical pre-drier. This material is fed at a prescribed rate into a high pressure roller mill and/or then into a ball mill where it is ground to the required finished fineness. Drying and milling can also be carried out in a vertical roller mill. Usually GGBS is ground to ...

The grinding medium in the mill repeatedly impacts and grinds the material by virtue of the kinetic energy obtained when the mill rotates. The crushed material is discharged into the suction tank through the tail of the ball mill, and then transported to the classifier for classification by negative pressure.

A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
