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 But there is another way. In fact, there are several proven solutions – centralised and decentralised – to this problem. ERDWICH machines and plant for swarf shredding and processing offer the highest levels of economic viability, safety and efficiency. With the decentralised solution, the ERDWICH swarf breaker is set up directly next to the lathe or machining centre. The swarf is removed and transported away to a central processing point either manually using a swarf cart or by means of pneumatic extraction, pumping or some other conveyor system. With the centralised solution, the swarf is collected in swarf carts at each machining centre and then transported to the ERDWICH master processing plant. This...

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. For many years now, ERDWICH has specialised in the reclamation of valuable primary materials from electronic waste with its shredding machinery and turnkey plant solutions. As a result, economical and mature solutions are available for meeting any of these challenges. ERDWICH pre-processing: Whether you’re handling electrical/electronic waste, small/large household appliances,...

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. With ERDWICH, you are assured of the latest technologically advanced solutions – even for the most demanding and safety-conscious refrigerator recycling. The...

According to initial estimates, in Germany about three million LCD monitors will be recycled in the year 2016. However, they often still have backlighting containing mercury and therefore have to be classified as “hazardous waste” in accordance with the German General Administrative Regulation (AVV) and registered in compliance with the German Electrical and Electronic Equipment Act (Elektro G) under category 3. Whereby special conditions must ensure that no risk arises from the mercury for the environment or for humans. However, because of a lack of suitable automated procedures for the recycling of LCD monitors, it was to date only possible to dissemble the appliances laboriously by hand, with the ensuing health dangers for the workers. For this, ERDWICH now offers two alternatives which are both safe and time-saving for recycling LCD monitors. Mercury and valuable resources can be removed and recycled in an environmentally sound way in the future: 1. Monitor sawing plant for...

Every year, Germany produces around 10 million tonnes of cardboard and paperboard for the packaging industry. After their use, these items of cardboard packaging and boxes must then be reduced in volume before passing through the recycling process. This volume reduction step is performed by recycling companies and public recycling depots or in cardboard packaging and corrugated board factories. Reasons for volume reduction: For these requirements, ERDWICH has developed a specialised product range – the EKZ and FKZ cardboard shredders – which can be supplied in a range of sizes. The ERDWICH plant items have been designed as a perfect match for downstream transportation systems. 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 into fragments of the desired size. The machines can also easily handle fruit crates and polystyrene...

Analytical shredding systems for QA work are a fundamental preliminary component in the production of substitute fuels. With primary fuels and finite resources subject to continuous price increases, the significance of substitute fuels continues to rise unabated. For plant operators, this offers first-class potential and attractive prospects for the future. Businesses that buy in their substitute fuel from external suppliers are faced with two key analytical requirements before putting it to use: pollutant analysis and calorific analysis. To ensure the proper handling of these analyses, a sophisticated sampling system is required. System criteria: To satisfy these requirements while ensuring optimum process reliability, you need a partner who possesses long-standing expertise and manufacturing proficiency.ERDWICH is that partner. Combining over 30 years of experience and the deployment of our proven single-shaft shredder, we have developed an automated, integrated system that...

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.

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:...

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.
