When processing electronic scrap, the aim is not merely to ensure the highest levels of process reliability and performance, but to salvage components such as capacitors and batteries intact where possible. Here, the the RM 1350/2 coarse shredder really struts its stuff: with the especially slow-running twin-shaft rotor/shredder system, the machine is especially resource-friendly and so ensures a large quota of intact capacitors and batteries. Two sizes of machine, with different shredder lengths and drive specifications are available to meet any challenge.

The uniform shredding of coarse materials: that’s the speciality of the ERDWICH three-shaft shredder. ERDWICH has created the three-shaft design especially for these requirements. Entirely free of clogging and jamming – even with solid materials. Clever, huh? Absolutely: after all, the three cutter shafts and their individual sets of blades rotate at different speeds, so as to continuously pull in and precisely shred the feedstock material. If the material is too large, the sweeper shaft simply transfers the material to the lower cutter shafts for further size reduction. Again and again – until the material is the exact size as specified. Tirelessly, and with perfect reliability. Fragment size selection itself is achieved by the perforated screen substructure through which the material exits after the shredding process. Precise shredding of large and solid materials. That’s what ERDWICH does.

Continuous-process shredding of large quantities and volumes: that’s the world of the ERDWICH two-shaft shredder. The secret of its success is our ERDWICH rotor-blade cutting principle, honed to perfection over decades. Want to know more? The material is taken up by the barbed blade, pulled unceremoniously into the machine and then shredded between the blades on the two opposing shafts. Whatever the material – e.g. special waste, WEEE, metal swarf, electrical waste or bulky items – even hard to shred, large-volume materials stand no chance against these two mighty cutter shafts. Perfect results are even guaranteed from fibrous, moist, heat-sensitive, elastic and rubbery materials. And, thanks to its mode of operation as a slow-speed piece of equipment, the ERDWICH two-shaft shredder also features quiet and largely dust-free operation. You can rely on the power and the technology of the ERDWICH two-shaft shredder. Continuous-process shredding of large quantities and volumes:...

Achieving precision material breakdown in just a single operation: that’s the proven capability of the Erdwich single-shaft shredder. How does it do it? The material is taken up by the cutting rotor and shredded repeatedly against the stator blade, using the tried-and-tested rotor/stator principle. This continues until the desired size has been achieved and the material can pass through the perforated screen underneath. The result is impressive: superior efficiency and optimum reliability for predefined fragment sizes. Choose the mature and highly economical technology of the ERDWICH single-shaft shredder for your application.
