(57) Disclosed is a limestone slurry and lime milk preparing device for hydrometallurgy of laterite nickel ore, which relates to the technical field of limestone slurry and lime milk preparation and comprises a limestone slurry preparation assembly and a lime milk preparation assembly. The limestone slurry preparation assembly comprises a first feeding machine, a grinding mill, a mixing machine, a first transfer pump, and a first buffer tank, connected sequentially. When the weight of the limestone slurry in the first buffer tank is not within a first preset range, the first feeding machine, grinding mill, mixing machine, and first transfer pump can adjust their respective operating speeds. The lime milk preparation assembly comprises a lime kiln, a second feeding ma­chine, a nitrifying machine, a third transfer pump, and a second buffer tank, connected sequentially. When the weight of the lime milk in the second buffer tank is not within a second preset range, the lime kiln, second feed­ing machine, nitrifying machine, and third transfer pump can adjust their respective operating speeds. The entire production line can respond in coordination, with overall automated adjustment of production efficiency and a high level of intelligence.
