A COMPLETE AND INNOVATIVE CONCRETE RECYCLING SOLUTION
CIRCULAR ECONOMY
A compressive crushing technology recognized for over twenty years for its performance across a wide range of minerals (particularly hard and abrasive minerals), the FCB Rhodax® 4D is now being used for a new process - recycling demolition concrete.
For this process, the technology’s unique selective grinding method easily releases the 3 components making up concrete: aggregate, sand and cement paste. Multiple tests have already been conducted for major industry figures, and the FCB Rhodax® 4D will start to industrially process demolition concrete for the first time in H2 2022 for the Heidelberg Cement group in Poland.
This unique stage in the circular economy offers multiple benefits, notably in terms of demolition product recovery: reusing aggregates and sand in new concretes, and reusing cement paste in the cement production process to create low-carbon clinker, or as a cement additive.
The released sand and cement paste components will also be recarbonated using the CO2 captured from cement plant gas emissions.
FCB Rhodax®’s selective material bed compression grinding process optimally releases the three components making up concrete - aggregates, sand (0.125-2 mm) and cement paste (0-0.125 mm), which will then be separated and retrieved.
FCB Rhodax® operation relies on the relative movement of the grinding chamber/cone, driven by the rotation of four unbalanced masses. They cause the external part (grinding chamber) to rotate. In this unique technology, the material elements being processed compress each other instead of being subjected to an impact, like most conventional crushers. This ensures optimal release, improved cubicity and a low wear rate.
