[0002] Calcium carbonate is an inorganic compound widely present in nature, with the chemical formula of CaCO. It is one of the main components of many rocks and soils, and is also an important component of many organisms. Calcium carbonate is widely used in industry, construction, medical treatment and other fields. In short, as an important inorganic compound, calcium carbonate is widely used in various fields. With the continuous advancement of science and technology and people's continuous exploration of the properties of calcium carbonate, I believe its application field will continue to expand and deepen.

[0003] Patent publication number "CN218689857U" discloses "a heavy calcium carbonate grinding device with an anti-adhesion structure", including a base plate, two of which are arranged in parallel, and the upper surfaces of the two base plates are fixedly connected with No. 2 support rods, and the upper ends of the No. 2 support rods on both sides are installed with grinding assemblies, and the grinding assemblies are fixedly connected with crushing assemblies. The worm is driven to rotate by the No. 2 motor. Since the worm is connected to the worm wheel ring through threaded engagement, and the worm wheel ring is fixedly connected to the upper surface of the grinding head, the grinding head can be driven to rotate in the grinding groove, thereby processing the calcium carbonate in the grinding groove.

[0004] If the device in the above patent uses only a single grinding head during the grinding process of calcium carbonate after crushing, the size of the particles after grinding may be fixed, making it difficult to achieve multi-size grinding. In order to improve the grinding efficiency, the multi-stage grinding head should be optimized and replaced. Utility Model Content
