For the defined shredding of voluminous and massive materials required for further operating or processing procedures, ERDWICH has developed the three-shaft technology. It is based on the proven rotor shearing cutting principle of the two-shaft technology.
Due to the different speeds of the three cutting rotors and to variable knife equipments, the materials are continuously pulled in and shredded – no jamming, no blocking.
Materials which are too voluminous are cycled by the overhead transfer shaft to the knife shafts below for further shredding. This circuit is repeated until the defined size of piece is reached.
The size of piece is determined by perforated sieves mounted under the machine through which the materials drop and are discharged after shredding. Three shafts – an optimal result: Exactly defined sizes of piece.
State-of-the-art technology for defined size reduction:
Individually inserted removable knife disks made of special knife steel
Fully hardened knives for long service lives and repeated regrinding
Smallest cutting gap between the knives for power-saving cut without jamming effect
Large-scale, precision milled hexagon knife shafts made of high-quality special steel
Compact, torsion resistant cutting gear housings
Rounded side panels which are adapted to the knife radius for reducing the strain on the shaft
Overhead transfer shaft for optimal self-cleaning effect
Separated drives for cutting rotors and transfer shaft
Sieve segments with individual hole geometries, adapted to the specific materials, mounted in a central, tilting sieve basket

Recycling Technologies Group | Recycling Solutions for Manufacturing Waste
Recycling is the future. There is no doubt. Clever recycling that provides sustainability both for the environment and the businesses operating in it is the way forward. A clean green and profitable future.
Companies are learning that good waste management not only safeguards employees and saves the environment; it is also turning into money.
Waste from manufacturing is inevitable and a significant by-product in the Australian industrial processes. Intelligent recycling of waste is emerging as a corporate governance issue of equal importance to that of long term company profitability.
The emphasis in now on responsibility in business, that of being a good corporate citizen.
Recycling can be a profitable operation, in many manufactuing facilities. Recycling and reclamation of cutting oils, emulsions and water for re-use makes strong economic sense. Processing waste materials such as metals, plastics and timber into a reusable resources results in profit straight back into the business
