Chromium trioxide is an inorganic compound with a molecular formula of CrO3. It is the acidic anhydride of chromic acid and is sometimes sold under the same name. The compound is a dark purple solid under anhydrous conditions, bright orange when wet, and dissolves in water with hydrolysis. Millions of kilograms are produced every year, mainly for electroplating. Chromium trioxide is a powerful oxidant and a suspected carcinogen.

  This machine can quickly mix materials with a certain water content such as easy to clot. The mixing speed is fast and the mixing effect is good. The machine adopts a new sealing structure inside, which has no pollution during the mixing process, simple structure and convenient operation and maintenance.

Characteristics of special double cone rotary vacuum dryer for chromium trioxide：

  1. Dry at low temperature under vacuum

  2. Due to the high coefficient of heat transfer, uniform drying efficiency in a short time is high.

  3. Solvent recovery can be carried out

  4. A specially designed micro air filter can be provided on the receiver while breaking the vacuum to ensure safe operation

  5. Due to the conical structure of the dryer, the drying material is easily discharged and the vibrator can be fixed

  6. The nitrogen purge system can optionally be used for mechanical sealing and cleaning filters.

  7. Specially designed S.S. rotary joints for hot water or steam at the inlet and outlet

  8. The heating method is indirect heating through steam, hot water or hot oil

  9. Self-cleaning butterfly discharge valve with safety blind cover

  10. Partial filter element filter for fine powder with effective surface area
