Kaolin Raymond Mill
The Kaolin Raymond Mill is specifically configured for processing kaolin clay into fine powder for paper, ceramic, paint, and rubber applications. Kaolin (china clay) is a soft, platy mineral requiring gentle, consistent grinding to preserve its platelet structure and maintain brightness. LIMING's Raymond mill, with its spring-loaded roller design and controlled grinding pressure, provides the ideal processing environment for kaolin. The mill produces 80-425 mesh powder with uniform particle distribution, preserving kaolin's natural brightness and whiteness that are critical for high-value applications.
Working Principle
Standard Raymond mill roller-ring grinding principle with optimized roller pressure for kaolin's soft, platy structure. Material is fed and ground between spring-loaded rollers and a grinding ring, with air classification separating qualified powder from coarse particles. The system's controlled pressure prevents over-grinding that could damage kaolin platelets and reduce brightness.
The grinding process is precisely controlled by the integrated classification system, which separates qualified fine powder from coarse particles. Coarse particles fall back to the grinding chamber for regrinding, while fine powder is conveyed by airflow to the cyclone collector and then to the finished product silo. This closed-circuit design ensures consistent product quality and high grinding efficiency.

Performance & Efficiency
The Kaolin Raymond Mill is designed for maximum grinding efficiency and energy savings. The optimized grinding chamber geometry, combined with high-precision classification, ensures that energy is used effectively for particle size reduction rather than wasted on over-grinding or heat generation. Compared to conventional milling systems, our equipment typically achieves 20-30% lower power consumption per ton of finished powder.
Key performance metrics include stable fineness control with deviation less than 5%, low noise levels below 75 dB at 1 meter distance, and dust emissions below 20 mg/m3 when equipped with our pulse bag filter system. These performance characteristics make our equipment suitable for even the most demanding industrial environments and stringent environmental regulations.
Installation & Commissioning
Proper installation is critical for optimal equipment performance and longevity. Our experienced engineers provide on-site installation and commissioning services, including equipment positioning, alignment, electrical connection, piping installation, and system integration. The typical installation timeline ranges from 15 to 45 days depending on equipment model and production line complexity.
During commissioning, we conduct comprehensive performance tests including no-load test, load test, and production trial runs. We verify all performance parameters meet design specifications, calibrate control systems, train your operators on proper operation and maintenance procedures, and deliver a complete commissioning report with all test data.
Frequently Asked Questions
Properly controlled grinding preserves kaolin brightness. Our Raymond mill's spring-loaded design applies consistent, moderate pressure that grinds without excessive heat or shear that could darken the product.
Yes. By adjusting the classifier speed, you can produce 325 mesh filler-grade or 1250 mesh coating-grade kaolin powder from the same machine.
