Maximum underflow density and overflow clarity with bolted construction options to expedite project delivery schedules.
Thickeners are used in continuous process applications where solid-liquid separation occurs by sedimentation.
Thickening has three basic purposes:
- Concentration, or raising the density, of a mixture of solids and liquids;
- Clarification, or recovering the overflow portion;
- Hydro-separation, where a specific fraction of solids is removed from a mixture;
CECMS can supply thickeners for a variety of applications. Some applications that we’ve been involved with include:
- Tailings thickening for precious and base metals & minerals
- Treatment of coal slimes
- Gold tailings applications
- Counter current decantation
- Clarifications of pregnant liquor solutions
- Water treatment applications
CECMS can supply a variety of thickener sizes starting from 1 meter diameter pilot-scale units to 90 metres in diameter. We have standard “off-the-shelf” designs, and customized thickener tank, rakes and feedwell designs that are deployed based on the feed conditions and raking capacity. A retrofit service has also been offered to enhance the performance of existing thickeners and clarifiers.
operational and technology benefits
Delivery time – our modular approach to thickener sizing means that drawing packaged can be assembled quickly and manufacturing can begin almost immediately. We have industry leading turn-around times.
Low capital cost – our equipment design is conservative yet robust enough to ensure the equipment can still be in operation many years from now.
International project delivery – our project team is experience deploying installations in challenging jurisdictions. Project expediting and construction schedules are kept in line because of multi-lingual and multi-disciplinary teams.
Canadian engineering/QA-QC standards – our engineering and design conform to the North American standards, but we’re able to leverage our network of manufacturers overseas to be competitive.
Bolted Design
CECMS can supply a “bolted design” for many projects to expedite fabrication, shipping and installation on site.
Bolted designs have the following benefits:
No construction works on site
Simple and easy installation
Easy to transport
Easy to re-locate and/or re-purpose
Low friction rake lift
