CANAMIX Mixers for Gas Dispersion
Many applications in Chemical Processing, Waste and Water Treatment, Food or Pharmaceutical productions, Petrochemicals and Minerals Processing, require the injection of gas into the mixing vessel. This can be air, oxygen, hydrogen, other gasses or a combination of gasses. The volume of gas introduced, and the rate of introduction is critical to both the efficiency of the system and the operation of the agitator.
Too much gas beneath the impeller can cause cavitation or ‘flooding’, resulting in poor dispersion, mechanical instability and solid settlement. Conventional aerofoil impellers, as used in convention leaching, blending, or general mixing, can only tolerate low volumes of gas before becoming ineffective.
The CANAMIX CHG4 high solidity, gassing impeller was specifically designed to accommodate the high gas requirements. Typically used in Bio-leaching, Hydrogenation, Fermentation, Cyanide Destruction and other similar processes, the CANAMIX CHG4 impeller has a high solidity ratio, meaning that the gas ‘sees’ a rotating disc, minimizing the amount of gas passing through the impeller.
The high pumping capacity of the impeller provides effective gas retention, meaning that the interfacial contact, between gas and solid, is extended. Older systems allow the gas to exit the vessel almost immediately.
In mineral processing the CAMAMIX CHG4 impeller is used in Bio-leaching, Cyanide Detox, Pressure Lead Reactors and in other applications where effective dispersion and retention of the gas is critical to overall process performance and efficiency.
