Coating Machine

This surface coating machine is used to treat non-metallic mineral powders and pigments so they perform more effectively as fillers or functional additives in downstream manufacturing. It is commonly applied in plastic compounding, rubber processing, adhesives, high-polymer composites, functional materials, and chemical additives where controlled surface modification is required.

The system operates continuously at industrial scale, combining powder dispersion and surface modification within a single process. Mineral powder and surface-treating agents are introduced together and subjected to high-speed vortex motion, allowing the modifying agent to uniformly coat particle surfaces while maintaining the original granule shape. This interaction enhances interfacial bonding between inorganic minerals and organic polymer systems.

By improving surface activity and compatibility, the machine increases filler loading capacity, strengthens mechanical performance, and supports more stable composite behavior. Efficient use of modifying agents reduces material consumption while maintaining a high active index and coating coverage, contributing to lower overall production costs and improved material performance.

The equipment is well suited for fine and lightweight powders such as white carbon, mica powder, and talcum powder, as well as denser mineral materials. Its enclosed, negative-pressure operating environment prevents dust leakage and supports clean, low-intensity operation in industrial facilities.

Operation is stable under both heated and ambient conditions, without the need for additional heating or cooling systems. The design supports large-scale, continuous production with straightforward operation and minimal environmental impact.
