ERDWICH Single-Shaft Shredder

ERDWICH hammer mills are the answer to the challenge of selectively shredding hard and brittle materials. Then again, ERDWICH hammer mills also take the pelletisation of rubbery materials – as preparation for downstream separation systems – in their stride. A tough customer? Just so. ERDWICH hammer mills are especially suited to metal, electrical and electronic scrap or swarf from steel or aluminium – and many other materials besides. Simple adjustability during operation also makes short work of the pelletisation of non-ferrous metals. The final fragment size is variable and can be changed during operation. That’s also a great example of the product’s flexibility in catering to a wide range of applications. For the selective challenges in life. ERDWICH hammer mills.

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.

Reducing transportation costs, compressing material for feeding to existing pressed-waste containers or baling presses, or shredding of material for conveyor belt feeding are good reasons for deploying a cardboard shredder. With the EKZ cardboard shredder and FKZ paperboard shredder, ERDWICH’s two rugged machines offer 100% process reliability in a range of form factors. Whether you need to shred packaging or process cardboard waste for feeding into existing conveyor systems, ERDWICH can always offer you a perfect solution tailored to your requirements.

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.
