The main topic is how to save costs when plastics are recycled.
The energy and operation costs have recently become decisive factors when plastics are recycled. Machine manufacturers have been called upon to find new solutions in this field. Herbold Meckesheim GmbH have done their homework and at the FAKUMA, will be presenting their new developments that have been produced at Meckesheim near Heidelberg, focusing on this aspect.
The construction design of the SMS Series from Herbold Meckesheim GmbH has been improved.
The construction design of the SMS series has been overhauled by Herbold Meckesheim GmbH so in future the machines of this series will even be able to cope with the most demanding heavy-duty applications in one single step.
These machines are manufactured with rotor widths ranging from 600 to 2000 mm and with drive capacities between 45 and 315 kW. The knife design is segmental, thus ensuring a quick and easy exchange of the cutting tools.
Typical applications are: heavy, thick-walled semi-finished products in PE, PP, POM and PA, pipes with high wall thicknesses and large purgings. Thick-walled materials are not the only materials that are quite difficult to recycle; the same applies to aramid fibres (commonly used for manufacturing bullet-proof vests), carbon fibres and composite materials, they are labelled as “difficult to grind”.
In case of heavy-duty applications, very often it is easy to separate the wheat from the chaff: there are only few suppliers in the market capable of providing an appropriate solution. The answer is the rotor design: only a rotor that has been forged as one single piece guarantees stability: welding seams cannot break since they do not exist. The rotor knives cannot shift since they have been fixed at a stopper. This design is also an enormous advantage for cleaning operations since there are no “dead spots” where material rests can deposit.
Herbold Meckesheim can supply wear-plated rotors and housings equipped with an exchangeable wear zone and thus leading to considerable cost saving compared to time-consuming armouring of the housing and rotor.
Developments from Herbold Meckesheim are ground-breaking. The wet grinding technique for granulators and many other recycling techniques that are the latest state of the art have been developed by Herbold.
Herbold Meckesheim will be present at FAKUMA 2015 (13.10. – 17.10.2015)
