摘要： Methods and a slaker for removal of heavy grit during batchwise slaking of burnt lime in a slaker (2) for the production of lime slurry with a high degree of fineness and prolonged sedimentation time are described, where the following processing steps are carried out during the slaking process: a)—reduction of the stirring of the slaker (2) from a normal stirring speed to a lower stirring speed, b)—opening of an upper inlet valve (60) in a collector (70) mounted in the lower part (54) of the slaker (2) to lead sinking grit in the slurry batch to the collector (70), whereupon the upper inlet valve (60) is closed after a given time period, c)—increase the stirring in the slaker (2) back to the normal stirring speed, d)—after a given time period with normal stirring speed, a regulating valve (22) in the lower part (54) of the slaker (2) is opened for emptying of a batch of slurry to an external storage tank (3), and e)—when said regulating valve (22) is opened for emptying of a batch of slurry, a lower outlet valve (62) in the collector is optionally opened for emptying of collected grit.

摘要： Method for the preparation of finely divided calcium hydroxide, where calcium oxide is comminuted in an impact disintegrator into which in addition to the calcium hydroxide a small amount of water is led to wet the particles obtained and to bind the dust. The calcium oxide powder is led to a conveyor being in connection with the impact disintegrator and operating as a pre-quencher, to which conveyer water is added and where the material is subjected to a kneading effect. The material which is a mixture of calcium oxide and calcium hydroxide is led from the conveyor to a cistern operating as post-quencher, to which cistern the remaining portion of the total water amount required for quenching is added. The amount of water added to the impact disintegrator and to the pre-quencher is altogether 20...50 % of the total amount of water required for quenching, preferably about 1/3 of the total amount of water required for quenching, and the amount of water added to the post-quencher is 80...50 % of the total amount of water required for quenching, preferably about 2/3 of the total amount of water required for quenching.

摘要： An improved lime slaker in which the lime is combined with the slaking liquor in a vertical conduit (18) which extends below the level of the liquor in the slaker vessel (10). The slaking liquor is introduced into the conduit at a high velocity tangential (26) to the interior surface of the conduit to flush the lime into the vessel. The slaker includes a vertical vent pipe (28) that extends through the bottom (14) of the vessel. In a preferred embodiment, the inlet of the vent pipe is surrounded by an entrainment separator (32). Removable covers (24, 36) permit convenient access for inspection and cleaning of the conduit and the vent pipe.

摘要： The invention concerns a method for the preparation of finely divided calcium hydroxide, where burnt lime or calcium oxide is comminuted in an impact disintegrator (10), into which in addition to the calcium oxide part of the required amount of water led to wet the particles obtained, to bind the dust and to initiate the reaction, and the material comminuted and wetted in the impact disintegrator is led into a screw conveyor (20) being in connection with the impact disintegrator. The invention is characterized in that - the reaction is essentially completed in the screw conveyor (20) by feeding into the same the remainder of the amount of water needed for the reaction, and that - the temperature of the material in the last part of the screw conveyor is kept at a target temperature, which is essentially the vaporization temperature for water at the prevailing pressure, and the material is kept at the target temperature for a certain period of time, about 5...15 s, preferably about 10 s.
