Abstract:
1. A method of treating lime slurry in a slurry treatment system, comprising the steps of: (a) providing a watery lime slurry having lime particles and grit particles therein, in a slurry tank; (b) delivering slurry from the slurry tank via a delivery line and extracting a portion of the slurry delivered from the slurry tank via delivery line and discharging said extracted portion of the slurry from said delivery line; (c) substantially continuously delivering slurry from the slurry tank to a device for gravity separation of some of the grit from the rest of the slurry without adding dilution water in the process; and (d) recirculating the rest of the slurry to the slurry tank after separation of some of the grit from the slurry.
