Innovation leap

A new generation feedwell with high solids retention & mixing efficiency that eliminates feed short-circuiting. It offers low shear for ideal floccule growth, even discharge symmetry & excellent feed preparation. As part of Planet Positive, the Reactorwell™ ensures low flocculant usage.

Has a unique channel and mixing jet design
Optimized with hundreds of industry leading CFD simulations
Covered by multiple global patents

How does it work?

Feed first enters the feed channel & is distributed evenly through the mixing nozzles
Dilution water flash mixes with the feed, achieving optimum percent feedwell solids concentration
Flocculant is introduced outside of the feed channel, where it gently mixes to form aggregates in a low shear environment

Unparalleled performance

The Reactorwell™ enables maximum thickener usage due to a higher exit symmetry, resulting in better thickener operability & improved response to process changes. It also enables improved overflow clarity with higher underflow density.

Performs exceptionally well in process scenerios where many current Feedwells struggle
Pictured is a 6m Reactorwell with incoming feed of 48% solids diluted to 10% without pumped dilution required
>90% of the volume is utilised for floccule growth
Delivers well mixed & evenly distributed exit flows even with large feedwells (>6m) & across a large solids fraction range
Many feedwell designs promise good symmetry but this is achieved with easier applications (small feedwells, no dilution, low feed % solids)

Cost excellence

Due to its intelligent design and modularity, the Reactorwell™ is easy to maintain. It consistently achieves high unit area throughput. The improved Autodil™ performance minimizes the need for pumped dilution. This all leads to a low total cost of ownership.

Flocculant usage is one of the highest running costs for a thickener. The Reactorwell™ features are proven to lower thickener running costs and has a lower environmental impact
Easy to maintain since the feed trough can be removed and replaced; maintenance can be more difficult with existing feedwell designs

A versatile high-performance upgrade

The Reactorwell’s design allows it to be integrated into existing mining operations as an upgrade that is compatible with most makes of thickeners. We offer expertise and support to retrofit existing infrastructure without major modifications. Read more here >>

The Reactorwell can also be upgraded to a new channel configuration if process conditions significantly change.
