S+S Metal Detector protects plastics
recycler
With rapidly growing demand for recycled pure PVC granules, metal detectors from S+S help protect valuable investments in plastic recycling machinery at Penfold Plastics
There's much talk about recycling but not always much action Down in Somerset, just outside Weston-super-Mare, Penfold Plastics, is doing much more than just talking about recycling, they are recycling 48 tonnes of PVC-u window frame plastic every weekday

New metal detection system is compact and low cost
The new Ecoline-D metal detector from S+S Inspection has been designed specifically for use with existing conveyor systems where space is at a premium
The PVC-u comes from several sources: extrusion manufacturers, window frame makers and window fitters.
The material is sorted, granulated into regrind, cleaned and delivered back to the extruders to complete the virtuous circle.
Sounds simple but it is a complicated process that requires a demanding combination of logistics, sorting, cleaning and processing to arrive at the high quality end product that the extruders will accept.

In the last three months, Penfold Plastics has invested over GBP250,000 in collection equipment, cages and roll on/roll off containers, plus the metal detection equipment, to keep up with the demand for their services.
When the material for processing arrives at the processing plant, it is first sorted by hand to remove any non-PVC-u material such as glass, metal, silicon sealant and insulating foam and to separate out any non-white plastic for separate processing.
The white material is then passed through an S+S Inspection Rapid Compact metal detector to remove any remaining metal that could damage the granulators used to reduce the white PVC-u to 6, 8 or 10 mm granules.
At this stage, the material is cleaned using a dust extraction system and passed through another S+S metal detector to remove any trace of ferrous metal swarf or "fines".
The completely metal free granulate is then passed though a colour sorter to separate out any remaining coloured or off-white material to leave a Grade 1 white granulate for delivery to extrusion manufacturers.
To get the quality that the Penfold Plastics customers demand, the Grade 1 granulate will be passed through the colour sorters two or three times.
The non-white fraction, known as "coex" is re-sorted to recover as much Grade 1 white material as possible and the remaining non-white material or "jazz" is bagged up for delivery to manufacturers of eco-friendly waste disposal and drainage products where colour is not an issue.
With over 25 years experience, Penfold Plastics is one of the more experienced PVC-u recyclers and has an enviable reputation for quality.
"We have always invested in the best equipment," says site manager, Jason Cockram, "because we simply cannot afford to be second best.
We chose the S+S Inspection metal detectors because they are easy to set-up and use, and they ensure that our output is 100% metal free". Request a free brochure from S+S Inspection ...
