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.
