  • High capacity mobile lime slaker
    Patent number: 6568842
    Abstract: A continuous preparation of calcium hydroxide slurry can be made on a mobile apparatus that uses an eductor to initially combine metered flows of calcium oxide and water. The calcium hydroxide slurry is retained in a deaerating sump and then pumped into a serpentine centrifugal mixer so that the reaction of the calcium oxide and the water is safely complete. Because the apparatus allows the calcium hydroxide slurry to be recirculated into the deaerating sump, the slaking process can continue even when it is necessary to pause the discharge of slurry to change transport tankers.
