   Kaolin, as an important non-metallic mineral resource, has increasingly wide applications. From papermaking and coatings to rubber and plastics, kaolin plays an indispensable role. The main mineral components of kaolin include kaolinite, halloysite, and sericite. 。

In the application process, modification is the key to enhancing its performance. In industrial production, professional coating modification equipment, such as “honeycomb mill”, plays an important role. A honeycomb mill is a mechanical and chemical continuous powder composite modification machine, integrating four functions: deep drying, depolymerization dispersion, composite modification, and powder spheronization. It has a mature and stable process in the field of coating modification.

Its main modification principle is to fully disperse and depolymerize the kaolin, and atomize and coat the modifier on the surface of the kaolin to form a nano-coating film, thereby completing the modification process. The coating rate of the honeycomb mill can reach 99.2%, and the activation rate reaches 99.8%。After kaolin is coated and modified by the honeycomb mill, its physical and chemical properties are significantly altered. For example, the whiteness, specific surface area, pore volume, oil absorption, covering power, wear resistance, insulation, and thermal stability are all improved. This greatly enhances the compatibility of kaolin with downstream polymer materials, effectively reducing or eliminating the embrittlement or performance degradation of downstream polymer materials caused by the addition of ultrafine aluminum hydroxide, and thus expanding the downstream Applications of ultrafine aluminum hydroxide flame retardants.

On the one hand, the honeycomb millThe efficient operation greatly improves production efficiency and can meet the needs of large-scale industrial production; on the other hand, its low energy consumption and low wear characteristics not only reduce production costs but also reduce the impact on the environment. At the same time, the equipment is simple to operate, runs smoothly, and the modular design makes maintenance and replacement of wearing parts very easy. The rotor blades and mill groove materials can be selected according to different materials, ensuring the wear resistance and service life of the equipment. It can not only help enterprises produce high-performance kaolin products to meet the needs of the high-end market but also stand out in fierce market competition and achieve sustainable development.
