‘Grit’ produced during slaking of quicklime can be handled in one of two ways:
- Separated at the discharge of the detention or paste slaker
- In a ball mill slaker the grit will be ground during the slaking process
Grit can be separated from the lime slurry using a vibrating screen, or with an inclined screw conveyor, with washdown. Grit separated this way will need to be collected and disposed of.
Alternatively, grit can be ground within a ball mill slaker to a particle size small enough carry on through the process without settling or causing abrasion/erosion.
