The waste wood is collected in large quantities at the recycling company’s premises and mostly fed directly into the shredder with a wheel loader or a digger. The digger operator first separates the metals etc. during the feeding process. The water spraying system on the shredder makes sure that there is none of the air-born dust usually found while processing wood. The aim here is to shred the material to previously defined output sizes ranging from 80 to 120 mm.

In single-step waste wood processing it is particularly important that the shredder is able to handle a variety of input materials since waste wood is often very bulky (e.g. large wood panels and broad boards). With its special double-shaft cutting/crushing principle and the aggressive intake necessary for broad and bulky pieces of wood, the URRACO series is the perfect waste wood shredder and with its fully welded shaft system it is the toughest machine for extremely difficult waste wood such as railway sleepers with solid iron sheets.

The magnetic separator fitted above the discharge conveyor safely extracts ferromagnetic parts such as nails, metal plates and hinges.

After shredding, the final particles are further classified. A defined particle size of usually <80 mm, <120 mm or according to the class in line with EN ISO 17225-1 are required for incineration in combined heat and power plants.

Thanks to an integrated system, the screened out oversized particles are returned to the shredder. This eliminates the need to transport the material back into the shredder with a wheel loader.
