분말 질화 및 기계화학적 활성화를 위한, 제어된 대기 환경과 최대 1100°C의 온도를 지원하는 OTF-1200X-R5-BM 회전식 볼 밀
The OTF-1200X-R5-BM is designed for advanced powder processing tasks requiring simultaneous high-temperature treatment and mechanical milling under controlled gas atmospheres. It is particularly suited for powder nitriding applications and mechanochemical activation of catalysts, such as those used in CO2 methanation, enabling the production of fully nitrided particles and rare-earth-free magnetic materials at temperatures up to 1100°C.
This system integrates a rotatable 5-inch diameter quartz processing tube equipped with four internal mixing blades to ensure efficient milling and mixing of powders. The tube rotates at variable speeds from 0 to 10 RPM, digitally controlled and displayed, allowing precise control over milling intensity. Ammonia gas or other reactive gases can be introduced through the tube to facilitate nitriding reactions during milling. The furnace features two independently controlled heating zones totaling 280 mm in length, providing a stable constant temperature zone of 100 mm with ±2°C accuracy when both zones are set identically.
