Description

Technical Field

[0001] This utility model relates to the field of nano-calcium carbonate production technology, specifically to a lime digestion device for proportioning and feeding in the production of nano-calcium carbonate. Background Technology

[0002] In the production of nano-calcium carbonate, it is often necessary to mix the raw materials lime and water to form a slurry so that the slurry can be used in the production of nano-calcium carbonate. The preparation of the slurry is generally carried out using a lime slaking machine.

[0003] Traditional lime digesters have a dispersing mechanism at the top, which can initially crush larger pieces of lime to improve the speed of the subsequent digestion reaction with water. However, the traditional dispersing mechanism cannot control the particle size of the lime, resulting in lime that is not fine enough and requires secondary grinding. At the same time, digestion cannot be carried out simultaneously during the dispersing process, resulting in low work efficiency. In addition, when lime is fed in a concentrated manner, material accumulation is likely to occur, affecting the dispersing efficiency. Further improvements can be made. Utility Model Content
