stoppage times of management systems, documents key quality data of the recyclates for the location manager, and informs operators about upcoming maintenance jobs. It is linked to Spare Parts Online, Erema’s online shop. Upcoming maintenance work – and the replacement of individual parts – is displayed in good time by Re360, allowing spare parts to be ordered directly and keep downtime as low as possible.
Smart analysis Next Generation Group – which comprises NGR, Britas Recycling and Dr Collin – is to showcase a range of new processing methods and innovative technologies at K2016. NGR’s Smart Dialog – which provides process
analysis – will feature in a live demonstration. Many evolutionary steps are increasing the output of NGR systems while providing lower energy consumption, says the company. Its P:React series will be presented for the first time, which follows the company’s earlier LSP process. It says that the technology allows it to make recycled pellets within minutes – which have better properties than virgin material. Britas, meanwhile, will present the latest version of its band-melt-filter, which is now easier to operate, supports more flexible applications and allows for minimal operating costs. “The activities and competencies of our individual

companies produce a unique combination that is highly sought after by research institutes, universities, plastic processors and recycling companies,” said Josef Hochreiter, CEO of the Next Generation Group.
Gentle cleaning Lindner WashTech says that its new Rafter system offers a gentle, efficient way to clean highly contami- nated, pre-shredded plastic waste by removing extraneous material and pre-washing the charge in one single step. It can be used in conjunction with the company’s Micromat WS wet shredder. There are three phases to the Rafter cleaning
process. First, a special conveyor screw pulls the contaminated material under the water surface so that heavy contaminants such as metal, stones or glass can precipitate. In a second phase, particles sticking to the plastic such as sand or soil are removed by a paddled rotor – whose rotational speed can be adapted to the degree of contamination. (This step is performed in a stationary drum, and separates floating or precipitated particles by means of plate screens.) After the washing cycle, the pre-cleaned waste rises to the surface, and delivered to subsequent process steps by a feed screw. The line has a nominal throughput of 1,500-2,500kg/h, and supports continuous in-line reconditioning of plastic waste all the way to the finished granulated recyclate or recycled film. The actual throughput can be adapted to the pace of upstream and downstream equipment with a frequency converter. It is cost-efficient to operate, thanks to its energy-optimised drive system and a water demand of only 3-10m³/h. “By integrating the Rafter into a recycling line to
pre-wash the plastic waste, operators gain an effective and economical method of reducing wear in down- stream reconditioning equipment,” said Harald Hoffmann, managing director at Lindner WashTech.
Modular shredders Rapid Granulator will introduce its Raptor series of plastics shredders at K2016. The modular units have a unique ‘open-hearted’ design, says Rapid. Other notable design features include its cutting system, a tilt-back hopper, and design for integrated granulation. “The Raptor series is a shredder and granulator hybrid with the shredder’s heavy-duty cutting technol- ogy combined with granulator features that make it easy to operate, service and clean,” said Bengt Rimark, sales and marketing director.
