In the powder modification process, most traditional gravity modification equipment uses electric heating or oil heating. This coating machine eliminates the need for external heating. The heat required for powder modification comes from two sources:

• Heat generated from air collisions: The high-speed rotor drives air movement, creating friction that generates heat. Without powder, air temperature at the discharge port reaches 60-65°C.
• Heat from powder interaction: The rotor, stator, and powder create collision, friction, and shearing that release significant heat. During normal operation, material outlet temperature ranges 90-130°C, sufficient for powder modification.

Modification temperature varies based on powder density, fineness, particle shape, and water content. This system eliminates external heating requirements, simplifying production and reducing costs by approximately 20% compared to traditional gravity modification equipment.

This machine modifies inorganic powder surfaces to enhance physical/chemical properties, improving compatibility and dispersion with organic polymers. It reinforces material strength and performance for powders (325-6000 mesh) including:

• Calcium carbonate (heavy/light)
• Kaolin, talc, fly ash
• Nitrogen oxide, sulfate, zeolite

Achieves >96% coating rate with minimal additives, no powder cohesiveness, and no particle size increase. Compatible with various ultrafine grinding mills.
