Kaolin clay is one of the most important industrial minerals, valued for its exceptional whiteness, fine texture, and stability. It plays a critical role in industries ranging from ceramics and coated paper to paints and cosmetics. To meet the rigorous standards of these sectors, kaolin must be processed with advanced grinding systems that protect brightness while delivering fine, uniform particles.
Key Processing Requirements
Maintaining Brightness: For high-end ceramics and premium coated papers, kaolin needs to retain an ISO brightness of 90% or higher throughout processing.
Precise Particle Control: A finely tuned particle size, typically D97 between 5 and 45 microns, is essential to achieve smoothness and performance without over-milling.
Low Contamination: Iron and other impurities must be minimized to preserve whiteness and chemical integrity.
MTW European Trapezium Mill Advantage
The MTW series (models MTW215, MTW218, MTW238) has been engineered to meet these exact challenges. Its standout features include:
Consistent Fineness: Optimized roller and ring geometry with curved duct design delivers narrow particle distribution.
Whiteness Retention: High-chromium alloy components and a fully sealed chamber prevent iron intrusion and external contamination.
Energy-Saving Operation: The bevel gear drive enhances efficiency, reducing power use by up to 30% compared with conventional Raymond mills.
Large-Scale Output: Throughput ranges from 3 to 50 tons per hour, ideal for industrial-scale kaolin production.
Smart Controls: PLC automation keeps grinding pressure and classifier speed under precise control, ensuring consistent product quality.
Conclusion
With its ability to balance fine particle size, high brightness, and low contamination, the MTW European Trapezium Mill is a leading choice for kaolin processors aiming to supply premium-grade materials for ceramics, paper, and beyond.
