Precision Silicon Nitride Ceramic Ball Mill Jar
• As a wear part for laboratory and production ball milling where metal contamination must be avoided, Precision Silicon Nitride Ceramic Ball Mill Jar resists acid, alkali and abrasive attack far better than metal or polymer alternatives.
• A machining tolerance of 0.005 mm guarantees an accurate fit, while excellent wear and corrosion resistance extends the service life of the equipment by 3-10x compared with metal parts.
• Available in a range of sizes and to customer drawings; batch quantities and tooling can be arranged on request.
1. Characteristics and advantages of product materials
• As a wear part for laboratory and production ball milling where metal contamination must be avoided, Precision Silicon Nitride Ceramic Ball Mill Jar resists acid, alkali and abrasive attack far better than metal or polymer alternatives.
• Excellent corrosion resistance, suitable for all kinds of acid and alkali conditions;
• Super hardness and fracture toughness of ceramic materials, products are not easy to wear;
• Neutral physicochemical index, no pollution to the ground material;
• Complex 3D modeling surface, five-axis five-joined surface.
2. Application
