Providing excellent aeration, mechanical simplicity, and CAPEX efficiency, WEMCO II self-aspirating flotation cells deliver highly productive and economic flotation performance. These robust workhorses of the flotation world are particularly suited to bulk rougher, high altitude, and molybdenum recovery applications.
The rotor in WEMCO II flotation cells is located at the top of the cell, resulting in a short travel distance to the launder for attached particles. This ensures highest possible recovery rates, particularly in bulk rougher flotation.
Self-aspirated flotation cells have no need for the blower and its ancillary equipment used in forced-air flotation applications, making WEMCO II cells a CAPEX-efficient choice for your flotation needs. In addition, the optimised design of the cells naturally creates efficient air dispersion and optimal circulation throughout the tank, optimising reagent consumption and for more cost-effective operations.
The mechanical efficiency of our self-aspirated flotation cells results in short maintenance downtime and costs. The rotor location at the top of the tank also means it’s not exposed to oversized material, further reducing maintenance and extending operating life. When rotor maintenance is needed, mechanisms can be changed without shutting down or draining the cell row, and rotors will restart easily under load.
The original WEMCO® cells earned their reputation for high recovery, easy operation, and low reagent use - and with over 40,000 units in the field it’s quite the reputation. But we saw room for more. The WEMCO II upgrade builds on that legacy with improved air control, greater froth stability, and better kinetics, delivering higher recovery and lower operating costs with enhanced control responsiveness.
We maintain a network of service centres close to our customers to offers long-term, full-lifecycle technical support. Our service engineers are always ready to travel to site for equipment inspections and audits, to supervise maintenance, and deliver tailored flotation training programmes. Meanwhile, our genuine WEMCO spare and wear parts deliver long service life and ensure the performance of your flotation cells does not degrade over time.
Optimized rotor and stator design reduces energy use while enhancing overall efficiency.
Top-mounted rotor allows easy maintenance without draining the cell or shutting down operations.
Extends operating life with recyclable rotor and stator components, supporting circularity.
