Abstract
This invention relates to an apparatus for the continuous preparation of aqueous solution of slaked lime solids with fresh water. The apparatus comprises a main vessel having an inverted truncated cone including a smallest and closed bottom. There is provided a dispenser for supplying material slaked lime solids to said main vessel at or nearly at the top end thereof from above, and a constant headed fresh water reservoir for supplying fresh water to the main vessel at a place selected therein in close proximity to the smallest bottom through a piping. A flow rate adjusting means is arranged in this piping. At least a mechanical or fluid agitator is provided at a close proximity to the vessel bottom. Means for the take-up of the formed product solution in an overflowing manner from the main vessel is provided at the top thereof.
