Inside Revtech: Questions About Our Industrial Solutions
What is the difference between calcination and drying?
Calcination goes far beyond simply removing moisture. It is a high-temperature thermal treatment that triggers chemical and physical changes in the solid, decomposing carbonates or hydroxides, removing bound water, binders or organics, oxidizing, or inducing a phase or crystal-structure change, all below the material’s melting point. Drying only removes free water; calcination transforms the material itself.
Is the Revtech calciner an alternative to a rotary kiln?
Yes, our continuous calciner is a 100% electric alternative to rotary kilns. It delivers continuous, uniform calcination with no combustion and no open flame, on a compact vertical footprint. For many powders and catalysts, it offers tighter temperature control, gentler product handling and a much lower carbon footprint than a gas-fired rotary kiln.
Can you calcine catalysts?
Yes, catalyst calcination is one of our core applications. The continuous system is suited both to fresh catalyst preparation (activation, removal of precursors and binders) and to the thermal regeneration of spent catalysts.
What powders and materials can you treat?
Beyond catalysts, our continuous calciner handles a wide range of fine powders and bulk solids (battery materials, metal oxides, ceramics, pigments, zeolites, alumina…). Its gentle vibratory conveying is especially suited to fragile or free-flowing powders that are difficult to handle in a rotary kiln.
What temperature can your continuous calciner reach?
Our system calcines with precise, programmable control of temperature and residence time along the tower, up to 700 °C.
Can you control the process atmosphere?
Yes, the fully enclosed design allows calcination under a controlled or inert atmosphere when your material requires it, for example to prevent oxidation.
How do you ensure uniform calcination?
The tower operates as a true plug-flow system with no dead zones, so every particle follows the same temperature profile and residence time. Continuous vibratory agitation keeps the powder evenly exposed from inlet to outlet, giving consistent, repeatable results run after run.
Do you offer trials before purchase?
Yes — we can run calcination trials on your own material at our pilot facility in France, with full reports, so you can validate the process and the results before investing.
