Question 1

What is a dual-shaft shredder?

Accepted Answer

A dual-shaft shredder (or twin-shaft shredder) is a slow-speed, high-torque shredding machine that uses two counter-rotating shafts turning at 13–20 rpm. The interlocking blades shear the toughest materials: wood, rigid plastics, tyres, WEEE, bulky waste, and cardboard. It is the go-to solution for multi-material volume reduction.

Question 2

How does a dual-shaft shredder work?

Accepted Answer

The two shafts rotate in opposite directions at low speed (13–20 rpm) with very high torque. The 55CrSi alloy steel blades interlock and shear the material through a pulling-tearing action. An automatic reverse anti-jamming system protects the machine from overload. The hardened gear reducer ensures power transmission even on the hardest materials.

Question 3

What materials can a dual-shaft shredder process?

Accepted Answer

The dual-shaft shredder is the most versatile in our range. It processes: solid wood and pallets, rigid plastics and films, tyres and rubber, WEEE (waste electrical and electronic equipment), bulky waste and furniture, cardboard and paper, mattresses, and SRF/RDF preparation (solid recovered fuels).

Question 4

What is the throughput of a dual-shaft shredder?

Accepted Answer

Euro Broyage's MBR range covers 12 models from 5.5 to 320 kW, with throughputs from 80 kg/h (laboratory model) to 50 tonnes/hour (industrial model). Actual throughput depends heavily on the nature and density of the material processed. Output particle size is typically 50 to 300 mm depending on blade spacing.

Question 5

What is the difference between a dual-shaft and a single-shaft shredder?

Accepted Answer

The dual-shaft shredder works by slow shearing with high torque — ideal for volume reduction of resistant materials without precise calibration. The single-shaft shredder uses a hydraulic pusher and calibration screen to produce calibrated, homogeneous output. In practice, both are often combined: the dual-shaft for pre-shredding and the single-shaft for refining.
