Abstract
A molten melt of slag and grinding material is introduced into a mixing chamber to which a cooling and mixing agent is injected, the agent being compressed air, water or an air/water mixture which serves to cool the melt and form vapor and solidified particles. These are passed through a diffuser and are discharged as a jet which is directed to particle disintegrating means.
Claims20
A method for granulating and disintegrating a molten melt of slag and grinding material, comprising the steps of:
- introducing the melt into a mixing chamber under pressure;
- injecting into said mixing chamber a cooling and mixing agent comprising at least one of compressed air, compressed water and a compressed air/water mixture to cool the melt and form a vapor and solidified particles;
- passing the vapor and solidified particles from the mixing chamber through a diffuser to form a first discharge jet of vapor and particles;
- and
- directing the jet discharged from the diffuser to means for disintegrating the particles, said disintegrating means being selected from a group including:
- (a) an additional diffuser discharging a further jet of vapor and particles in a path which intersects said first discharge jet whereby particles in the respective jets collide and disintegrate;
- and (b) a baffle plate positioned to be impinged by particles carried by at least said first jet.

Apparatus for granulating and disintegrating a molten melt of slag and grinding material, comprising:
- a mixing chamber:
- means for introducing the melt into the mixing chamber under pressure;
- means for injecting into said mixing chamber a cooling and mixing agent, comprising at least one of compressed air, compressed water and a compressed air/water mixture, for cooling the melt to form a vapor and solidified particles;
- a diffuser joined to the mixing chamber for receiving the vapor and solidified particles from the mixing chamber and discharging them from the diffuser as a first jet of vapor and particles;
- and
- means for disintegrating the particles, said disintegrating means being selected from a group including:
- (a) an additional diffuser discharging a further jet of vapor and particles in a path which intersects said first discharge jet whereby particles in the respective jets collide and disintegrate;
- and (b) a baffle plate positioned to be impinged by particles carried by at least said first jet.
