CCW offers multi-stage washing for high recovery and low moisture cake
CCW Filters are key to getting the best results out of your circuit. Our horizontal belt filters will lower costs, increase circuit recovery and provide the operational simplicity and service reliability you demand. With more than 700 units installed, FLSmidth has more experience than any other manufacturer.
What we offer
We are the world leader in installed CCW filtration applications
Effective technology
The better your filters, the more pure the cakes that come from Counter Current Washing (CCW). Our rollerdeck horizontal belt filter (HBF) design provides your operation with the best process performance at the lowest maintenance and power costs.
Maximizing Soluble Metal Recovery
There a multiple variables that can affect your soluble metal recovery and capex. We conduct an analysis of each of the following variables to make sure that each piece is optimised for your application.
- Particle size distribution
The particle size distribution (PSD) determines whether the application should use filtration or thickening technology. If your operation needs filtration, then you’ll need filters. If not, then you ] would use our CCD Thickeners.
- Suspended solids distribution
The suspended solids distribution comes from the thickener or horizontal belt filter. If suspended solids distribution is high, then the wash efficiency will also be high.
- Wash ratio
We check to make sure that the wash efficiency is high by gauging the amount of wash water. The more wash water, the higher the efficient.
- Number of thickeners or wash zones
Efficiency is also increased by the number of thickeners or horizontal belt filter wash zones in a circuit. We check to make sure that there are enough thickeners or wash zones for the application.
- Wash liquor soluble metal concentration
The soluble metal concentration should be low in order to optimise wash efficiency.
- Interstage mixing efficiency
When efficiency is high for the Interstage Mix Tanks, the wash efficiency is also high.
Full service capabilities
- Testwork
Research and testing is needed to plan an efficient operation. We perform testwork on technologies and perform material characterization to ensure that we go in prepared.
- Flowsheet and equipment selection and sizing
The proper flowsheet design and accompanying equipment will keep all the pieces of the circuit functioning well together. We create a reliable flowsheet and carefully choose the right equipment.
- Technology design
Effective technology transforms an operation. Our experts use leading tools to quickly deliver technology designs to your team.
- Fabrication
Conventional fabrication can be time consuming. Our team leverages our international locations to save costs and time on fabrication.
- Installation
Similar to fabrication, installation is often costly and forces operations to extend deadlines. To save time and money, we send expert supervision to oversee the installation. We also recommend pre-assembled HBFs to save on installation time.
- Commissioning
To get your operation functioning quickly, we offer start-up and commissioning support.

Product Features
The CCW Filter technology behind the results
Improperly designed and installed Horizontal Belt Filters can be costly and require considerable power. Our world leading installations and the FLSmidth rollerdeck design solves these common issues. The drainage belt in our rollerdeck is supported by low-friction rollers, providing a perfectly horizontal belt and filter cake level while using the lowest drive power consumption possible. This considerably reduces the maintenance and power cost for FLSmidth horizontal belt filters without sacrificing product quality.
