How do you handle grit produced during lime slaking?

‘Grit’ produced during slaking of quicklime can be handled in one of two ways:

  1. Separated at the discharge of the detention or paste slaker
  2. 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.
