Powder Surface Modification Coating Machine

Continuous powder coating machine for optimizing particle features

Powder surface modification coating machines generatw heat through high-speed interaction between the rotor and materials, effectively modifying the surface of powder particles. It operates under negative pressure, enabling continuous production with high throughput, low energy consumption, and minimal use of coating agents. Its high activation index makes it a strong alternative to traditional high-speed mixing machines, and it has become the preferred choice for surface modification of powders from 325 mesh to nanoscale.

Applications

Material enters the powder coating machine (surface modification) through the feeding system, while the modification agent is added using a metering pump. Inside the powder coating machine, both the material and agent undergo high-speed mixing multiple times. The heat generated by the rapid motion of the equipment and the material enables the modification agent to coat the powder’s surface. The final product is then collected through a negative pressure collection system.

Features
  • Supports continuous production with a large throughput. It can operate independently or be integrated with various ultrafine grinding machines
  • Achieves a high coating rate and activation index, with minimal consumption of coating agents
  • Prevents particle agglomeration, eliminating the need for additional screening and allowing direct packaging of the modified product
  • Modification temperature can be adjusted based on the specific material properties
  • Operates under negative pressure, preventing dust emission and ensuring a clean working environment

Working Principle

The feeding system introduces the material into the powder coating machine, with the modification agent being metered in simultaneously. Inside the chamber, repeated high-speed mixing occurs, utilizing the heat from the rapid movement of both the equipment and material to ensure the modification agent thoroughly coats the powder’s surface. The finished product is collected via a negative pressure system.
