Abstract

This disclosure relates to a method for continuously and proportional adding of lime to a water flow through in a plant, wherein a number of slakers are used for batchwise slaking of burnt lime, and wherein lime slurry with a greater degree of fineness and prolonged sedimentation time is produced. A first slaker empties completely slaked and diluted lime slurry after the weight principle proportional to the water flow through of the plant, until a predetermined mass of slurry weight is left, which is used for mixing with a next batch. A second slaker, which is ready for its emptying sequence, starts emptying completely slaked and diluted lime slurry after the weight principle proportional to the water flow through of the plant, when the first slaker has finished emptying, until a predetermined mass of slurry weight is left, which is used for mixing with a next batch. After flushing with flushing water via valves of respective slakers, production of a new batch is started, this is ready for its emptying sequence when the active slaker has finished its emptying.
