Second use: materials recycling & granulators
A wide range of recycling machinery – from granulators to shredders – have recently been introduced to the market, extending the choices available to end users
In the face of the Coronavirus epidemic, K2019 may seem a distant memory but it remains the most recent major platform for technology launch- es, including all kinds of recycling machinery – ranging from shredders and granulators to full recycling lines and a variety of sorting machinery.
Magnetic performance Bunting Europe showcased its expertise in magnetic separators and metal detectors for the recycling and plastics industries. In virgin plastic manufacturing processes, metal damages processing equipment and the quality of the end-product. Recycled plastic commonly has both ferrous and non-ferrous metal contamination, and removal is vital to enable the reuse of the waste material, says the company. Bunting’s portfolio includes a wide range of magnetic separators and metal detectors to detect and remove metals. Its FF and HF drawer filter magnets are the most commonly used magnetic separators in the plastics sector. Visitors saw both standard and manual- clean (MSC) designs, which all use high strength neodymium iron boron (rare earth) magnets. In operation, plastic beads or shredded plastic waste falls through the drawer filter under gravity, while ferrous metal is attracted to the magnets.

The company displayed its new FF350 drawer filter magnet in Europe for the first time. The FF350 enables processing material at higher tempera- tures. High heat is damaging to standard rare earth magnets and the new design maintains magnetic strength at temperatures up to 350F (175°C). There are also changes to the housing, window and access fixings to provide trouble-free operation at these temperatures. The company also displayed the plate magnet (with and without tapered step) and grate magnets (round and square). “Our experience in solving metal contamination issues in the plastics sector is second to none,” said Simon Ayling, managing director of Bunting Europe. “Without removing metal from waste, the recycling of plastic is simply not possible.”
Technology evolution CMG made K2019 the platform for the launch of its new Evoluzione series of granulators for post-con- sumer recycling.
It said the new EV916 and EV616 models are high-performing, versatile, efficient and sustainable. The model on display at K2019 was the EV616, a nine-tonne machine with sufficiently moderate dimensions to be positioned in the stand. Giorgio Santella, general manager for sales and
