Steam-Activated Rotary Tube Furnace

Steam-Activated Rotary Tube Furnace

This advanced steam-activated rotary tube furnace integrates a high-temperature rotary furnace (up to 1200°C, 3–7 RPM) with a built-in steam generation system, designed for continuous physicochemical processing of powders and granular materials. Combining uniform heat distribution, energy efficiency, and precise steam control, it excels in applications requiring simultaneous thermal treatment and steam activation, particularly for R&D of Li-ion battery cathode materials (e.g., LiFePO₄, LiNi₀.₅Mn₁.₅O₄) and inorganic compound calcination.
