RASOR Single-shaft shredder - post-shredding

RASOR
The Concept The RASOR is a post-process shredder for the generation of refuse-derived fuels from pre-treated waste fractions. The continuous material feed using one or more feed augers ensures uniform power consumption. The material is shredded by slow-running cutters in the enclosed shredding unit in a virtually dust-free process. The automatic cutting gap adjustment guarantees minimum energy consumption during the shredding process. Minimal downtime is ensured by tool-free exchange of the counter-cutter, all wearing parts and screen baskets.
• continual material feed with automatic cutting gap adjustment for uniformly low power consumption • exchange of wearing parts without the need for tools means minimal servicing times • retractable counter-cutter carrier provides optimal service accessibility • low rotor rotation speed ensures shredding with low levels of dust and vibration

Material feed Up to three feed augers with load-dependent control transport the material into the shredding area. Material is pressed continuously against the shredding rotor – in contrast to competitive products which operate intermittently. This guarantees consistent power consumption. Dust emissions are prevented due to the enclosed shredding area.
Shredding system Material is presented to a slow speed rotor with cutters in the shredding area and cut at an opposing knife. Particle size is defined by the screen baskets around the rotor. The rotor itself is built from a carrier tube with segment plates. If the rotor is damaged by a massive contaminant, only the affected, low cost segments have to be replaced. The dual-purpose cutters are fixed in axially running seating slots in the segment plates and are not screwed on to the rotor.
Automatic cutting gap adjustment The counter-cutter is held by a hydraulic clamp. Servo-motors automatically control the feed of the cutting edge to the rotor cutters and provide accurate positioning with minimal cutting gap. This results in a permanently low energy consumption during the cutting with a positive effect on energy costs. Savings up to 30 per cent can be achieved, in comparison to competitive machines.
Quick-change systems Exchange times are minimal due to the avoidance of bolted fixings. On the optional automatic cutter-change system, a new cutter is pushed hydraulically into the seating slot and a used one is ejected. The screen baskets are inserted and then positioned by a clamping system. The baskets are made from simple laminations and are dual-purpose.
