Description

Technical Field

[0001] The utility model relates to the technical field of nano calcium carbonate, in particular to wet grinding equipment used for the production of nano calcium carbonate. Background Art

[0002] Wet grinding is to grind natural calcium carbonate once or twice, wash it, select it, and then grind it in wet grinding equipment. Then, mix it with grinding aids and grind it again. After screening and precipitation, the product is obtained. Its production advantages are low production cost, large-scale production, low cost; the product particle size can reach an extremely fine particle size. However, wet-ground calcium carbonate products are difficult to transport, so wet products should be produced and used on-site. Controlling the humidity of calcium carbonate during wet grinding is more important for the quality of the final product. The existing wet grinding equipment is centrally filled with water, which makes the humidity distribution of calcium carbonate uneven, resulting in poor product effect. In addition, the open material port will cause calcium carbonate dust to overflow every time the material is added.

[0003] The patent with the patent announcement number CN218013112U discloses a wet grinding device for the production of nano calcium carbonate. The utility model includes a fixed base, a machine, a main motor, a gear reducer, a gear roller, a cylinder, and a calcium carbonate material pipe. The machine is fixed on the fixed base for carrying the driving components. The main motor and the gear reducer are fixed on the machine, and the output shaft of the main motor is connected to the input shaft of the gear reducer. The gear roller is rotatably arranged on the machine, and the output shaft of the gear reducer is connected to the gear roller through a coupling. A rotating frame is fixedly arranged on the fixed base symmetrically. The calcium carbonate material pipe passes through the second feed opening and is added into the dust reduction sleeve and added into the multi-faceted main cylinder under the action of the inclined surface in the dust reduction sleeve and the feed spiral sheet, and the humidification water is added into the multi-faceted main cylinder by the water supply pipe. The above patent has the following shortcomings: although the patent can grind the calcium carbonate raw material, it cannot shake and filter the calcium carbonate particles after grinding and grinding, because the size of the calcium carbonate particles after grinding and grinding is not uniform, which will lead to the decline of the quality of the finished product. In view of this, we propose a wet grinding device for the production of nano calcium carbonate. Utility Model Content
