[0002] Calcium carbonate activation treatment refers to improving the physical and chemical properties of calcium carbonate by physical or chemical methods to improve its performance and effects in various applications. Calcium carbonate is a common inorganic compound that is widely present in nature and has good chemical stability and thermal stability. However, ordinary calcium carbonate powder has limitations in dispersibility, plasticity and transparency. Calcium carbonate activation dry surface modification treatment is a surface modification method in which calcium carbonate powder is directly mixed with a modifier and stirred in a dry environment.

[0003] The coupling agents used in the dry surface modification treatment of calcium carbonate activation treatment mainly include titanate and aluminate coupling agents, as well as silane coupling agents, phosphate coupling agents, etc. These coupling agents can react with the characteristic groups on the surface of calcium carbonate to form chemical bonds, thereby improving the performance and interaction of the material.

Through the rotation of the rotating shaft 16, the mixing barrel 14 and the injection hole 45, the coupling agent powder and the calcium carbonate powder are continuously ground, so that the coupling agent powder and the calcium carbonate powder are fully mixed and more delicate.
