A menu-guided control system permits variable settings to be programmed and operating modes for different materials (as a function of their specific properties) to be stored in memory. Even the most difficult material can be shredded reliably and without problem. 

• Minimum cutting clearance brought about by the precise and secure knife fastening system 

• Simple and self-centring fastening of the cutting knives 

• High impact strength brought about by the knife seats milled into the shaft 

• Modular design 

• Self-cooling during rotation 

• Cutting power and cutting pressure can be set to suit the task in hand 

• The cutting frequency/speed of the shaft can be regulated 

• Power control with blockage and reversing value specifications 

• The feed and return speed of the pusher drawer can be set 

• The discharge rate can be adjusted to suit downstream units 

• Granule size definition at minimum undersize and oversize portions 

• Different knife designs and numbers of knives available 

Because of the positive engagement of the knife blades with respect to the knives on the opposite side, materials such as plastic film or fibres are stripped reliably and cannot wind themselves around the shaft. 

Dependent on the problem specification, patented, distortion-proof knives with different profiles are available. The hydraulic drive ensures smooth operation, even in the face of extreme loads. The speed is steplessly adjustable and permits optimum adjustment to the size reduction task in hand.
