Alternative Fuels (RDF) : Shredders

Alternative fuels – waste-to-energy (RDF)

Alternative fuels are becoming increasingly more popular – for a good reason. For one, they serve as fractions of high heating value for energetic use as outlined in national and international laws. Furthermore, they substitute scarce and expensive fossil fuels, and that not only in energy intensive industries.
To produce alternative fuels, fractions of high heating value recovered from domestic waste, bulky waste, commercial waste as well as remains from recycling processes and industrial waste are used.
Particular attention is paid to the carefully separated light fraction, which yields the major part of the overall heating value. Its characteristic as two-dimensional carrier and the low absorption of humidity determine the quality of the fi nal alternative fuel.

The essential specific material characteristics of the alternative fuel are decisive for the plant’s layout and the functionality of the applied technical solutions.

Our qualified products for processing alternative fuels (RDF):

V-EBS 2500

V-EBS 2500

The Vecoplan shredder for residue derived fuel (RDF) V-EBS 2500 was specially developed for re-shredding light plastics obtained from industrial, commercial and municipal solid waste and requires very little maintenance or servicing. The final particle size is impressively homogeneous. The machine is equipped with the patented HiTorc drive, which permits variable speed adjustment. Particularly notable are the large rotor diameter of 1,000 mm and the extremely high mass moment of inertia of 1,270 kg m². These features allow lots of torque even when processing tough material, They also grant smooth and quiet operation. It is also very economical to operate thanks to a comparatively low power consumption and low wear costs. The screen mesh sizes are normally between 25 and 50 mm. Depending on the mesh size, throughputs of between 10 and 22 to/h can be achieved.

VVZ-Hurricane

The VVZ (210, 300) double-shaft shredder is a pre-shredder for processing difficult waste and material containing tramp material, such as pallets, boxes, cable drums, demolition wood, items of furniture, chipboard, and municipal solid as well as commercial waste. The two solid steel rotors with a diameter of 500 mm maximise the throughput. The machine is equipped with the “Flipper”, a pneumatically pre-tensioned counter knife that prevents damage if tramp materials are fed in. This also makes it easy to remove tramp material without having to unload the hopper. The degree of reduction can be set via adjustable screen bars. Depending on the input material, throughputs of between 6 and 25 to/h can be achieved.

VVZ Hurricane (210, 250, 310)

The VVZ Hurricane (210, 250, 310) double-shaft shredder is a pre-shredder for difficult waste and material containing foreign objects, such as domestic and commercial refuse, production waste or old wood. The large filling chamber accepts large bales and bulky materials. Two solid steel rotors with a diameter of 720 mm and high mass moment of inertia ensure smooth, quiet running with high throughput. The interaction of the two rotors with the shared counter knife and screen grid produces a homogeneous particle size with excellent separability. The machine requires minimal maintenance and servicing, also because wearing parts are easy to replace. Two large hydraulic access doors make wearing parts easier to replace and allow foreign objects to be removed, even when the feed hopper is completely full. The degree of reduction can be set via adjustable grid bars. Depending on the feedstock, throughputs of between 10 and 100 to/h can be achieved. In addition to the standard hydraulic drive, the patented HiTorc drive is also available, which reduces power consumption by up to 60%. The drive capacities range between 2 x 132 kW and 2 x 200 kW and rated torques of up to 60,000 Nm.

Single Shaft Shedders- Small Series

Single-shaft shredders, small series

Single-shaft shredders (VAZ) small series: VAZ 800, VAZ 1100
The single-shaft shredder is the most versatile and widely used shredder and can operate without an additional feeding system in most applications. The material collected can be fed directly with dosing. The hydraulically driven ram feeds the material to the rotor. The rotor system, developed and patented in 1989, is able to handle almost all materials.

The rotor of the single-shaft shredder (VAZ) turns particularly slowly and this, combined with the vertical material feed, makes it especially quiet and dust-free. The large- volume hopper and the patented rotor system optimise the shredding of wood, plastic, paper and other recyclables.

Single Shaft Shredders : Medium Series

Single-shaft shredders, medium-duty series

Single Shaft Medium Duty Shredders: VAZ 1300, VAZ 1600, VAZ 1800, VAZ 2400
The single-shaft shredder is the most versatile and widely used shredder and can operate without an additional feeding system in most applications. The material collected can be fed directly with dosing. The hydraulically driven ram feeds the material to the rotor. The rotor system, developed and patented in 1989, is able to handle almost all materials. Optionally, the machines of this series can be equipped with a Flipper, which grants security against damages caused by tramp material and also makes it easy to remove the tramp material. Additionally they can also be provided with a bridge-breaker for the shredding of bulky and light materials.

Small and sturdy: Our medium-duty single-shaft shredders can gain an impressive throughput of up to 6,000 kg/h, which is far from average.

Single Shaft Shredders : Heavy Duty Series

Single-shaft shredders, heavy-duty series

Single Shaft Heavy Duty Shredders: VAZ 2000, VAZ 2500
The single-shaft shredder is the most versatile and widely used shredder and can operate without an additional feeding system in most applications. The material collected can be fed directly with dosing. The hydraulically driven ram feeds the material to the rotor. The rotor system, developed and patented in 1989, is able to handle almost all materials.
