Metal detectors speed plastics recycling
An
Eriez Magnetics Europe product story

One of Europe's largest manufacturers of plastic systems recently installed three Eriez tunnel-type Model 20C metal detectors at its UK headquarters.
Wavin, one of Europe's largest manufacturers of plastic systems for the building, construction and utilities industries, recently installed three Eriez tunnel-type Model 20C metal detectors at its UK headquarters in Chippenham, Wiltshire.
Wavin looked to Eriez to provide a solution to metal contamination which would also ensure a steady and continuous feed of recyclable material to their granulators.
Wavin collects and store plastic waste, comprising sprues and other waste parts, in large storage bins.
Before being fed to granulators the contents of the bins are decanted onto an inclined inspection table where any oversized pieces are removed and water is drained out from the material through the table's perforated deck.
Before the Eriez Model 20C metal detectors were installed this plastic waste had to be hand-fed into the granulators and manually checked for any metal contaminants.
Now, the material is tipped on to the metal detectors' 'intralox' conveyor belts, specially fitted with friction strips, and passed through the metal detectors.
If no metal is detected, the material then falls down an integral chute into the granulator.
However, if metal is detected the belt stops and a combined siren/beacon is triggered to signal which of the three metal detectors has tripped.
All three metal detector units are fully mobile giving maximum versatility on site.
