The decision for shredding machines, hammer mills and plant engineering by Erdwich.
In deciding for a single-shaft shredder from Erdwich you are also deciding in favour of years of experience and expertise in the development of recycling equipment.
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.
The Single-Shaft Shredders from Erdwich are manufactured in various sizes – M400, M600, M700 and M800, each of which is available with cutting equipment in a variety of sizes.
Continuous-process shredding of large quantities and volumes: that’s the world of the Erdwichg 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.
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.
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 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.
Light, easy to use and, most importantly, fully recyclable – cardboard boxes are becoming increasingly popular as packaging material The members of the Corrugated Cardboard Industry Association (Verband der Wellpappen-Industrie) alone sold around 1.9 billion square meters in the first quarter of 2017. However, recycling used cardboard boxes can be problematic, not least because the folded cardboard boxes are becoming increasingly large and require a lot of space. Therefore it is useful for packaging manufacturers and service providers to use a special shredding facility to shred cardboard boxes and to simplify the disposal process. The EKZ cardboard box compacter used by Erdwich Zerkleinerungssysteme GmbH is ideal for shredding cardboard. Thanks to its low-maintenance chain drive, wear-resistant tearing segments and a scraper system that was specially designed for this application field, it has high availability and is extremely reliable.
The high demand, particularly for cardboard solutions, creates a logistical challenge: Several tons of cardboard need to be shredded every month. In the past, the flattened waste cardboard came directly out of the production machines without being shredded by a cardboard shredder and was fed into a paper container.
The Erdwich cardboard shredder happily accepts not just cardboard but also fruit crates, polystyrene packaging and other types of packaging.
The EKZ has two shafts with independent drives: one high-speed shredder shaft and one slow-speed feed-in shaft. The feed-in shaft feeds the packaging to the shredder shaft, which then shreds the cardboard in double-quick time. In addition to the standard setup – a standalone machine that is either hand- or belt-fed – the EKZ cardboard shredder can also be set up to work in tandem with pressed-waste containers.
The Erdwich paperboard shredder forms the ideal add-on to the EKZ cardboard shredder. Thanks to its efficient shredding process it is ideal for trouble-free feed-in, directly at the point where waste is created.
Material such as cardboard waste from production machinery or punches can thus be directly fed into existing extraction-based conveyor systems. With the FKZ, Erdwich
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.
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.
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.
Our standards are clearly expressed: For every application the perfect solution.
As every customer requirement is different: Volume, field of application, through-put, technology grade and a lot more parameters are considered individually during designing each construction. For metal swarf, e-waste, refrigerators, fuel surrogates, cartons or special waste – thousands of plants in operation enthuse our customers. By highest economic efficiency and functionality. Day per day. In our test center we have the possibility to test every field of application and every further solution under real conditions. Benefit from our experience and competence.
In metal-working shops utilising swarf-producing manufacturing techniques, the generated swarf is often an underestimated cost factor:
This means your expensive machine tool cannot attain its full productive potential.
The key challenge here is therefore: Process reliability
One of the greatest challenges facing our society is the reclamation of valuable raw materials from electrical and electronic scrap.
A global scrap volume exceeding 40 million tonnes a year – a figure forecast to double by 2025 – presents both a challenge and an opportunity. Since even in Germany only some 40% of scrap is currently fed into a waste management process, we may assume that the global rate of waste management is still substantially lower.
With additional support from WEEE Directive legislation, this represents enormous growth potential for recycling companies in all consumer-oriented markets.
Several million scrap refrigerator units are disposed of every year in Germany alone. The proportion of refrigeration units recycled by volume totals about 40% and is the most significant segment after consumer electronics.
One particular challenge in this recycling process is presented by chlorofluorocarbons such as R 11, R 12 or R 141b, which were used for decades as foaming agents for insulation materials. Since these substances damage the Earth’s ozone layer when released, they must be removed and collected securely in a closed-system pre-processing plant.
The fact that pre-processing of legacy refrigeration units always needs to be carried out in accordance with the latest technological standards means that plant operators gain a decisive advantage when working with an innovative and experienced plant manufacturer.
Every year around 10 million tonnes of cardboard and cardboard are produced in Germany for packaging purposes. In terms of recyclability, the industry is one of the pioneers: approx. 70% of all paper products are mostly made from waste paper. A paper fiber can be reused about seven times before it becomes unusable for paper and board making.
Reasons for volume reduction:
Storage media containing confidential data and information are very diverse. Digital media play an increasingly important role in our era alongside the classic data carrier paper.
All too often, however, hard disks are handled very carelessly when old equipment is disposed of. The result is that valuable information falls into the wrong hands and may cause substantial damage running into millions.
The DIN standard 66399 takes this diversity into account and defines safety for all modern media and describes the requirements for both machines and processes for the destruction of data carriers. Standard-compliant destruction of stored data can only be achieved by mechanical destruction of the device. A recovery of data from the shredded devices is thus rendered impossible.
Acids, alkalis, solvents, isocyanates - Anyone dealing with hazardous substances and transporting them in containers is always faced with the problem of proper disposal of the containers in the end.
For a long time, the common practice of reconditioners was to dismantle used and non-reusable containers after cleaning and either recycle or dispose of each substance separately. The plastic inner containers were collected and transported by truck to the waste incineration plant. However, this method caused very high transport and disposal costs. Large-volume containers such as 200 litres barrels, refuse containers of up to 1.1 cbm, IBC containers with a capacity of up to 1.5 cbm, car bumpers and other large plastic parts can, though, be returned to the recycling process by targeted processing.
Ever-increasing consumption across Europe, coupled with rising prosperity among the populations of the typical emerging economy are causing a sharp upturn in the volume of waste worldwide.
Our shredding machines are perfectly suited for processing
The shredding of solid waste materials represents an important process step in recycling technology.
For the analysis of a sample, it is often necessary to reduce its size during sample preparation.
The screenings cause considerable problems during disposal. In its untreated state, it is very moist and still contains a considerable proportion of easily degradable organic matter, which can lead to unpleasant odours due to spontaneous decomposition processes.
In a sewage treatment plant, pieces of wood, plastic foils and other heavy materials are fed in via the waste water inlet. These are collected with the screenings in front of the screens and are then removed from the waste water stream during the screen clearing process.
In order to dehydrate the screenings as much as possible before their disposal, it is necessary to shred the material. This increases the surface area of the material and improves subsequent drying. For this shredding process, twin-shaft shredders are generally used.
