What is a lime slaker, and do I need one?​

A lime slaker is a machine designed specifically to control the reaction of water with quicklime (called ‘lime slaking’) to produce Calcium Hydroxide (CaOH2) or Hydrated Lime slurry. If your process uses lime slurry and you will have quicklime (CaO) delivered, you will need a lime slaker to carefully control the slaking reaction and the resulting lime slurry reactivity.

We generally recommend one of three types of lime slakers (and they each have applications where they are better suited):

  1. detention slaker
  2. paste slaker
  3. ball mill slaker

If you will be using less than 4 tonnes/day of lime, then you may be able to use hydrated lime and will not need a lime slaker.
