High Wear‑Resistant Low‑Contamination Grinding Rotor Silicon Nitride Ceramic Rotor for Sand Bead Mill
Replace conventional metal rotors with high‑performance silicon nitride (Si₃N₄) ceramic rotors to upgrade your bead‑mill grinding performance.
Manufactured from high‑density sintered silicon nitride, this rotor features exceptional mechanical strength, high fracture toughness and excellent thermal‑shock resistance, reliably sustaining high‑speed rotation under heavy‑duty grinding conditions. Its ultra‑low wear rate drastically reduces metal impurity ingress into ground materials, making it perfect for high‑purity nano‑grinding and dispersion processes.
Si3N4 Ceramic Parts are a man made compound synthesized through several different chemical reaction methods. they are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.
■ Superior High-temperature Stability
Main Applications:
High-temperature furnace protection tubes, thermocouple insulating sleeves, metallurgical molten metal conveying and shielding tubes, semiconductor thermal processing equipment, new energy high-temperature modules, chemical anti-corrosion piping and industrial high-temperature insulating structural parts.
