RDF production line



rdf-pre-shredPre-shredding process materials into a homogeneous particle size also cut the over-lengths for subsequent processing steps.

Two-shaft shredder could duel with those complex wastes in a perfect way. The torque of shaft is large enough to cut any materials.



Ballistic separation


After pre-shredding, materials is treated by separation systems.A conveyor belt feeds a rotating sieve to sort hard and abrasive materials (mainly glass and inert) unfit for the RDF production.

Ballistic separator, sorting the heavier fraction destined for landfill or incineration from the light fraction, more suitable for the production of RDF.


Separation of recycables

rdf-ballistic-separationPotential recyclables, or fractions high in calorific value, can be separated off from the rolling fraction for post-shredding using inductive and optical sorting systems.

Use magnetic separation to sort ferrous metals.

Use eddy current separation to sort non-ferrous metals.


rdf-fine-shredThe material after separated is then collected on a belt conveyor feeding the single-shaft shredder, which has a screen with 30 mm grate in order to limit the size of the material sent to the next steps.

The shredder could produce efficiently with equipped hydraulic ram to enforce feeding.



rdf-pellet(briquete)At last, the shredded material is followed by an elevating belt feeding the hopper of pelleting extruder.

In the extrusion chamber the material is subjected to high friction and pressure, generated by the rotating screw mixers, and is then pushed through an extrusion matrix, which determines the shape and size of the product.
