PRODUCT
DESCRIPTION
Chenxing Recycling Machinery delivers precision metal detection solutions with our 4-in-1 Metal Removal System, engineered to protect shredders and granulators from ferrous/non-ferrous metal damage. The Tunnel Magnetic Detector identifies contaminants as small as 5x5mm in bulk materials, triggering instant system shutdown via vibration-resistant controls. Paired with our Over-Belt Magnetic Separator and Eddy-Current Separator, this industrial-grade suite achieves 99% metal removal efficiency – ideal for plastic recycling lines and regrind operations.
Featuring adjustable sensitivity and anti-interference wood racks, our CE-certified detectors prevent false alarms while reducing equipment wear by 40%. The Drum Magnetic Separator scatters materials evenly for continuous purification, compatible with PVC/PP/PE flakes. Customize belt widths (300-2000mm) and frequencies to handle wrapped metals or end-of-life auto parts. Backed by 20+ years of expertise, Chenxing’s smart metal removal systems slash maintenance costs by 50% and ensure FDA-compliant output for food-grade recycling.
ADVANTAGES

FAQ
1. What is the purpose of using a metal detector in a plastic recycling line?
The metal detector is used to identify and eliminate ferrous and non-ferrous metal contaminants in plastic waste streams. It protects downstream equipment such as shredders, granulators, and extruders from serious damage and ensures product purity in recycled plastic pellets or flakes.
2. At which stage of the recycling line is the metal detector typically installed?
It is commonly installed:
-
On or under the belt conveyor, before shredders or crushers
-
Before feeding into extruders or pelletizers
-
After bottle bale breaking or film compacting
It can be adapted to various points depending on line configuration and material flow.
3. What types of metals can it detect?
Our systems can detect:
-
Ferrous metals (e.g., iron, steel)
-
Non-ferrous metals (e.g., aluminum, copper)
-
Stainless steel particles, depending on sensitivity and calibration
4. What plastic materials is the detector compatible with?
The metal detector can be used for:
-
PET bottle flakes
-
HDPE/LDPE films
-
PP, PE rigid plastics
-
Mixed plastics from post-consumer or industrial waste
5. How does it respond when metal is detected?
Once metal is detected, the system can trigger:
-
Audible and visual alarms
-
Conveyor stop or reversal
-
Pneumatic reject mechanism to remove contaminated materials
The reaction type depends on the model and system integration.
