The original Mixtec EDICT (Energy Distribution In Cylindrical Tanks) system, developed in 2005 in Mixtec’s Research and Development facility in South Africa has been trialed and successfully installed in literally hundreds of mining applications worldwide.
The system consists of Mixtec’s latest high efficiency, down pumping impeller together with an up-pumping impeller. This adds velocity to solids initially suspended by the lower impeller, by drawing them into the low-pressure area created and ‘boosting’ the upward motion to the upper portion of the tank. The solids then travel across the slurry surface to overflow or back down toward the flow generated by the lower impeller to repeat the cycle.
The system correctly utilizes a combination of specially designed up and down pumping impellers to result in extremely effective and efficient suspension of solids. As with all our designs, various factors (tank dimensions, particle sizes, process temperatures, liquid levels, agitator impeller designs, shaft and drive) are calculated and sized for each specific application.
Mixtec is considered by many as, ‘setting the benchmark’ in power consumption and effective agitator equipment technology in the mining and refining industry, therefore it remains the superior choice for agitation.
APPLICATIONS
Homogeneous Solids Suspension: Requiring only 75-80% of the power of a traditional Dual Down-Pumping impeller configuration.
Solids Suspension with Low Volume of Gas: Opposing flows further hinders gas from raising around the annulus of the tank resulting in greater gas hold up.
Solids Suspension with High Volume of Gas: Using our HA736, wide blade impeller, designed for high gas volume in addition to our EDICT System allows for greater gas hold up and improved kinetics within the tank.
