Quadrate Foam bonded line

Model:HHR-1A (with system for steam)


 


Description:

ReboTec - recycling of trimmings
"ReboTec is a process, in which slab stock waste and trimmings are comminuted into flakes, then compressed into PU-bonded rectangular or cylindrical blocks that are subsequently cut to size. "

Foam grinding:
" Grinding is a recycling process, in which foam trimmings are converted into loose flakes(by our HHRG-22/11).These are then ground into a powder through shear action in a roller mill. Larger particles are filtered and then fed to the mill until all particles fall into the specified < 0.2 mm fines fraction. The regrind powder can then be put in intermediate storage containers (silos).
The performance data of a crushing system for large-scale industrial use shown on the left are impressive: upto300 kg flakes are ground into powder of lessthan0.2 mm grain size every hour. The on-line metering unit feeds up to 70 kg of powder per minute into the polyol stream. With a second metering unit running in parallel, up to 140 kg of powder per minute can be processed. "

rebonding process
"The trimmings are shredded into flakes before being wetted with a polyurethane adhesive, then blended in a mixer and discharged into a mould. Since the loose flakes have a significantly lower bulk density than the finished block, the flakes are compressed inside the mould. Rebounded foam is subsequently formed by adding hot steam and pressure. "

Broad density range
"The density of the finished blocks ranges between about 80 and 120 kg/m3. Block densities of up to 500 kg/m3 are feasible with a suitable flake preselection and special equipment"

Advantages:
Production of a new, profitable high-quality product
Environmentally compatible recycling technology
Almost full re-use of all trimmings obtained in slabstock manufacturing
Homogeneous integration of PU flakes into the foam cell structure
