Abstract:
A method to prevent build-up of limestone in a slaker that is used for batchwise slaking of burnt lime is described, in which lime slurry is produced with a greater degree of fineness and prolonged sedimentation time, where for immediate cleansing of the slaker before next slaking, after said calibration of the load cell aggregate, a number of valves are opened for given time periods for addition of flushing water to respective nozzles, in that flushing water is supplied sequentially via each valve to associated nozzle(s), until a predetermined amount of flushing water is reached in the slaker.
