CANAMIX applies experience-based knowledge and technical expertise to providing high quality fluid mixing systems for use in the mining, chemical, pharmaceutical, paper, and waste & water treatment industries.
Whether an application requires flow, gas dispersion, chemical reaction, solids suspension or a combination of any of these, there is a CANAMIX agitator specifically engineered for the duty!

The conventional SX system provides a pump box, incorporating a pump mixer, to introduce the aqueous and organic mediums into the settler. The system can also contain an auxiliary mixing chamber to allow secondary mixing of the solutions, prior to flowing to the settling chamber itself.
The CANAMIX SX pumper produces a combination of head and flow to ensure adequate mixing of the solutions and effective transfer from the pump box.
Our in-house design program has access to the performance of dozens of impeller types and geometries. This allows the selection of the most suitable for the specified duty. SX pump mixers and auxiliaries need to be fine-tuned for optimum performance, usually requiring a VFD.
Too much mixing can cause surface air entrainment.
Too little mixing can cause phase separation.
So, selecting the correct combination of power, speed, and impeller type make the difference between an effective mixer settler and an under-performing system.
The CANAMIX pump mixer for the SX settler incorporates a radial flow pumper impeller, with either flat or curved blades. The blade width is selected according to the head/flow requirements of the process. Dependent on the geometry of the pump box, an upper auxiliary impeller can be fitted to the shaft to improve mixing and, in many cases, reduce power requirements.
The design of the system requires an inlet orifice, matched to the impeller diameter, to ensure optimum performance and maximized efficiency.
The clearance between the bottom of the pumper impeller and the separation plate is critical. The clearance can be as small as 12mm (1/2”). Accordingly, minimum shaft deflection is advisable. For this reason, CANAMIX SX pumper mixers use drives with extended bearing housings to ensure that deflection is not an issue.

Where a secondary mix box is required on a mixer settler system, usually to improve initial mixing prior to the settling chamber, CANAMIX mixers use dual or triple aerofoil combinations dependent on tank geometry. These impellers are always up pumping to eliminate air entrainment.
The CANAMIX CHFU aerofoil impeller, used on the Secondary tanks, is a version of the successful CHF322 aerofoil impeller used in hundreds of mixing applications. Its low power, high flow characteristics make it ideal for use in Secondary mix boxes on SX settler systems.

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.

CANAMIX can provide the design and manufacture of various sparging systems for the introduction of gas into agitated vessels, dependent on the amount of, and type of, gas. For example:
The installation and assembly of large agitators can involve extensive rigging, mechanical handling and extensive man hours. CANAMIX can assist with the design and provision of special assembly jigs and procedures which can reduce assembly time substantially, often by more than 50%.
CANAMIX engineers have many years of experience in the design of mechanical agitators and have been involved in the replacement of numerous problem installations.
CANAMIX can survey any existing plant, experiencing agitation problems, and provide a written report on methods to improve the systems. In one example, an existing gold plant improved their recovery by more than 5% after replacement of their agitators with CANAMIX systems.
CANAMIX can provide in-house training of personal involved with the plant agitators to increase the knowledge base and minimize agitation problems. This training has proved invaluable where operational staff have better understood the benefits of:
