Inorganic powders—such as calcium carbonate, talc, kaolin, and magnesium hydroxide—have become core fillers in a wide range of industries, including plastics, rubber, coatings, and construction materials, owing to their abundant sources, low costs, and stable performance. However, untreated inorganic powders have inherent drawbacks: their surfaces are highly polar, resulting in poor compatibility with organic matrices (such as plastic resins and rubber substrates). When added directly, this can lead to uneven dispersion within the material and a decline in mechanical properties. Moreover, certain powders suffer from issues such as moisture absorption and caking, as well as inadequate weather resistance, severely limiting their application in high-end products.

Meanwhile, the coating and modification machine, through precise surface modification treatment, can enable inorganic powders to... “Base Filler” has been upgraded to “Functional Enhancer,” perfectly tailored to meet the processing requirements of high-end materials.

The coating and modification machine utilizes the synergistic effects of high-speed mixing and air-classification to first disperse agglomerated inorganic powders into monodisperse particles, while simultaneously removing trace amounts of moisture and impurities from the powder. At the same time, the equipment employs a precise metering system to evenly spray modifiers—such as coupling agents, silanes, fatty acids, and others—in an atomized form onto the powder surface, ensuring that every particle comes into full contact with the modifier. Relying on the equipment’s unique chamber structure and specially designed stirring speed, it achieves... Synergistic effect of “mechanical force + thermal energy”—the mechanical force promotes chemical bonding or physical adsorption between the modifier molecules and the active functional groups on the powder surface, while the thermal energy accelerates the reaction process, thereby forming a uniform and dense organic coating film. The entire process allows for precise control of the coating thickness (typically ranging from nanometer to micrometer levels), ensuring consistent modification effects.

The application of coating and modification machines in inorganic powder processing features three core characteristics that perfectly align with the industry’s actual production needs:

Highly versatile and compatible with a wide variety of powders: It can process various inorganic powders, including calcium carbonate, talc, kaolin, bentonite, magnesium hydroxide, aluminum hydroxide, wollastonite, and more. Whether the powder is light or heavy, ultrafine or of conventional particle size, ideal modification effects can be achieved by simply adjusting process parameters—no need to replace core equipment.

High modification efficiency and flexible, adjustable production capacity: Adopting a continuous production design, the daily production capacity of a single unit can be flexibly adjusted from several tons to dozens of tons, meeting both small- and medium-batch trial production needs as well as large-scale mass production requirements. Compared to traditional batch-type modification equipment, this approach significantly improves efficiency. More than 30%, and with higher uniformity of modification, thereby avoiding performance variations between batches.

Easy to operate and highly process-controllable: Equipped with an intelligent control system that enables real-time monitoring of key parameters such as temperature, rotation speed, and modifier dosage. The system supports parameter storage and recall, thereby lowering the skill requirements for operators. Meanwhile, the equipment features a well-designed structure that facilitates disassembly, cleaning, and maintenance, reducing downtime.

After being treated by the coating and modification machine, the inorganic powder exhibits significantly improved compatibility and more uniform dispersion. 、 Enhanced mechanical performance, upgraded product quality. 、 Optimized processing fluidity, enhanced production efficiency 。
