Abstract
A compact lime slaker has an inner vessel forming an initial slaking chamber disposed in an outer vessel forming a final slaking chamber, with agitators provided In both chambers. Slaked lime from the final slaking chamber is pumped to a collection trough where slaked lime and grit are removed therefrom, while a major portion of slaked lime, with grit removed is returned to the final slaking chamber. The slaked lime in the final slaking chamber, at an elevated temperature due to the slaking exotherm, insulates the lime being slaked in the initial slaking chamber and provides heat thereto to aid in the initial slaking. Removal of grit from the portion of slaked lime recycled to the final slaking chamber prevents clogging or attrition of components of the slaker.
