As the core equipment for resource recycling, the Scrap cable granulator machine plays an important role in the environmental protection industry and renewable resources.
It transforms plastic-containing insulating materials such as discarded cables and wires into high-value recycled plastic particles through specialized physical and chemical treatment processes, realizing the transformation from "industrial waste" to "recyclable raw materials". The following is a detailed explanation from three aspects: technical principles, application scenarios, and market value:
Technical principles and processing flow
Scrap cable granulator machine adopts a multi-stage processing system, mainly including:
Crushing and separation section: The cable is decomposed into 5-10cm fragments by a strong tearing machine, and a magnetic separation/eddy current separation device is used to extract copper, aluminum, and other metals
Cleaning and drying system: Friction cleaning + chemical paint removal process is used to remove surface oil and impurities
Melt extrusion unit: The twin-screw extruder realizes plasticization of plastics in the temperature range of 180-280℃
Pelletizing and molding module: The water ring pelletizing or hot pelletizing system produces 3-5mm uniform particles
Closed-loop application in the power cable industry
Processing objects: Cross-linked polyethylene (XLPE) insulation material, PVC sheath material
Regeneration value:
Low-voltage cable: Recycled particles can replace 30% of new materials for 0.6/1kV cable sheath
Overhead wire: After modification, it is used for the insulation layer, and the volume resistivity is ≥1×10¹³Ω·cm after detection
High-end modified plastic development
Innovative application:
Flame retardant modification: Add aluminum hydroxide to make V0-grade flame retardant particles
Alloy material: Blend with PP to produce automotive wiring harness conduits
Manufacturing of new environmentally friendly building materials
Product matrix:
Plastic-wood composite materials: 60% recycled PE + 40% wood powder to make outdoor floors
Building templates: Engineering plastic templates produced by a multi-layer co-extrusion process
Extended value chain creation
Metal recycling value-added
Copper recovery rate ≥99%, purity Cu ≥99.9%
Economic calculation: 300kg of copper can be extracted from each ton of waste cable, worth 18,000 yuan
Carbon reduction benefits
Compared with virgin plastic, 2.5 tons of CO₂ emissions are reduced per ton
EU certification: Comply with ELV Directive 2010/53/EU standards
