This initial stage is crucial for energy efficiency in subsequent grinding. Product materials include primarily sodium feldspar minerals (albite) with minimal quartz and mica impurities. 2. Grinding & Milling: The crushed ore is then fed into ball mills or vertical roller mills for fine grinding. This mechanical process reduces the material to a fine powder, targeting specific mesh sizes (e.g., 200 mesh to 325 mesh, or even finer for specialized applications). The grinding media and speed are optimized to achieve uniform particle size distribution, minimizing fines and coarse particles. This process is optimized for minimal energy consumption. 3. Classification: After grinding, the powder passes through air classifiers or screens to separate particles based on size. This ensures that the final product meets precise particle size specifications, which is critical for applications like glazes and high-performance ceramics. 4. Purification (Flotation/Magnetic Separation): To achieve ultra-high purity, especially for low-iron applications, advanced beneficiation techniques are employed. Froth flotation selectively separates feldspar from associated minerals like quartz and mica using chemical reagents. Magnetic separation removes ferrous impurities, ensuring the pristine white appearance and optical clarity required in glass and ceramic glazes. 5. Drying & Homogenization: The purified slurry is dewatered and then dried in rotary kilns or flash dryers to achieve a moisture content typically below 0.5%. The dried powder is then homogenized in large silos to ensure consistent chemical and physical properties across batches. 6. Quality Control & Packaging: Throughout the entire process, rigorous quality control checks are performed using XRF (X-ray Fluorescence) for chemical composition, laser diffraction for particle size, and other analytical methods. The final product is packaged in moisture-resistant bags (e.g., 25kg, 50kg, or bulk bags) according to customer specifications, ready for dispatch. Testing Standards: Our manufacturing processes and final product adhere to international standards such as ISO (International Organization for Standardization) for quality management and product specifications, and often meet specific industry standards like ASTM (American Society for Testing and Materials) or customer-defined parameters.
