Abstract
A slaker includes a substantially straight, circular sidewall, a substantially flat bottom, and a top. A solid and a liquid feed inlet are disposed at the top of the vessel and an outlet is disposed at the bottom of the vessel. Apparatus is provided for mixing the solid and the liquid within the vessel at high speed and separate apparatus is provided for sweeping the bottom and sidewall of the vessel at low speed. The mixing apparatus and the sweeping apparatus apply substantially only horizontal forces to the solid and the liquid being mixed within the vessel. The slaker further includes apparatus for recirculating at least a portion of the solid and the liquid being mixed within the vessel which flows through the outlet and apparatus for discharging the resultant mixed solid and liquid from the slaker.
