Product Overview
This multi-zone continuous rotary furnace is engineered for the calcination of 5N ultra-high purity powders, ensuring zero metallic contamination and stable industrial-scale operation. It features a 1050℃ design temperature, five independent temperature zones for precise thermal profiles, adjustable rotational speed and inclination, and an integrated dust collection unit for environmentally compliant, clean production.
Key Advantages
Purity & Contamination Control
High-Purity Quartz Tube (Φ300/Φ290 × 5500 mm): Inert SiO₂ composition prevents metallic ion contamination, ideal for Fe- and Al-sensitive materials.
Enclosed Design + Controlled Atmosphere: Optional inert gas protection minimizes oxidation and impurity intrusion.
Dust Collection Integration: Captures particulate emissions during calcination to meet environmental standards.
Precision Thermal Management
1050℃ Max Design Temperature: Covers most high-purity material requirements with a 50℃ safety margin.
Five Independent Heating Zones (±1℃): Enables tailored heating curves for preheating, reaction, sintering, and controlled cooling.
SCR + PID Power Control: Fast response to thermal fluctuations, avoiding overshoot and improving efficiency.
Flexible Process Control
Variable Speed & Inclination: 0–15 rpm rotation and 0–3° tilt to adjust material residence time.
Segmented Heating & Cooling: 3500 mm heating zone plus 1000 mm forced-air cooling section for product stabilization.
Dynamic Power Distribution: 60 kW total power output optimized based on load and heating demand.
Industrial & Energy Efficiency
0.5 t/day Throughput: Suitable for medium-scale high-value powder production.
