EKATO is the world leader for autoclave agitation technology. EKATO offers customized solutions and has valuable experience in autoclave applications worldwide. The EKATO autoclaves offer a robust mechanical design and high quality manufacturing (titanium clean room for welding). We offer a complete range of mechanical sealing solutions and seal support systems for autoclave trains. Autoclave technology is used when extraction by classical atmospheric leaching methods is not economical

We offer customized agitator solutions for atmospherically gassed mining tanks that impress with their efficiency and cost savings. Our innovative agitator and mixer gassing concepts enable considerable savings in terms of compressor performance, among other things, which in many cases can lead to savings on entire compressors. This not only considerably reduces the investment costs of the overall system, but also significantly lowers ongoing operating and energy costs.

From our wide range of gassing agitators, we can always offer the optimum and most efficient solution, specially adapted to the required gas quantities, the suspension challenges and at economical prices.

Our VISCOPROP and ISOJET-B hydrofoil impellers are ideal for low to medium gas rates. For high gas rates, the particularly efficient EKATO COMBIJET and EKATO COMBIJET PLUS solutions are used, which have a very low power loss even with high gas volumes and enable a cost- and energy-efficient agitator design.

Our optimized aeration concepts prevent flooding of the agitators and clogging of the aeration holes, which is a common problem with conventional aeration rings. The improved dispersion significantly increases the mass transfer, which leads to more efficient processes and shorter production times.

Overall, these advantages contribute to a significant reduction in the operating and maintenance costs of the system.

Ceramic blades on a metallic hub: that is the solution, how even large impeller diameters can be realized. This has been proven their worth especially in ore processing.

Modern engineering ceramics open up completely new perspectives. Advances in ceramic processing allow the construction of impellers with diameters of 2 m and more. Even complex geometries can be realized. Depending on the size and shape of the impeller, it can be designed as one solid ceramic part, or alternatively ceramic impeller blades are connected to a metallic hub. This composite construction is permissible since wear always occurs in the area of ​​the highest speeds, which is on the outer edge of the impeller.

Why Technical Ceramics?

Technical ceramics offer many benefits compared to metal or rubber coating materials:

• Significantly higher hardness and strength

• Very high chemical resistance

• Very good resistance to thermal shock

• Lighter than corresponding metal components

Your Advantages

All these material properties lead to significant advantages, especially in highly abrasive applications.

• Drastically longer product service life

• Significantly less service intervals

• Massive savings potential in operational costs

Leaching tanks & atmospheric tanks

As rich ore deposits are diminishing and demand for raw materials continues to grow, the processing of low-grade ores is becoming increasingly important. An unbroken development here is the expansion of production units in order to be able to process the increasing throughputs more economically. The large agitators required for this must be very robust and reliable in order to ensure plant availability even over several years in rough everyday operation. The mixing tasks range from demanding suspension tasks with high solids loads to the homogenization of pasty suspensions with non-Newtonian flow properties. Typical applications are:

• Leaching tanks, e.g. gold-bearing ores (CIL, CIP) and non-ferrous metal ores (zinc)
• Homogenization of non-Newtonian suspensions with high solids content, e.g. in storage tanks for autoclaves as well as storage and intermediate tanks for slurry pipelines
• Mixing and conditioning tanks, e.g. CCD intermediate tanks, mashing of filter cakes
• Storage and buffer tanks to compensate for production fluctuations

What are the advantages of our agitators and mixers for atmospheric mining tanks?

Our agitators and mixers are specially designed for the extreme requirements of mining. Our mechanically robust agitators and mixers are precisely designed for the various operating conditions required. Whether operating in various critical filling levels with significantly increased forces on the agitator, high solids concentrations and different particle sizes, we always design our agitators with sufficient safety.

Our experts offer comprehensive advice and conceptual design to optimize the operating mode with regard to fluctuating dynamic forces, energy efficiency and challenging suspension tasks. This guarantees trouble-free and efficient operation of your system.

The flow-optimized impellers ensure efficient mixing and thus ensure a process flow and prevent deposits in the tank.

Our impellers are available with various coatings (such as rubber coatings, wear-resistant silicon carbide materials…), are extremely resistant to wear and corrosion, which extends product service life and significantly reduces maintenance intervals. This means you benefit from lower operating costs and higher system availability. If our customers have extreme abrasion problems, our industrial ceramic impellers are the proven solution!
