I. Overview of Wire Waste Sorting Machines
wire waste
Wire waste sorting machines are environmentally friendly machines specifically designed for processing waste wires and cables. They can separate the metals (such as copper and aluminum) and plastic insulation layers from the wires. This type of equipment is suitable for various types of waste wires that are difficult to process directly with wire strippers, including automotive wiring harnesses, communication cables, household wires, and miscellaneous wires. Its key feature is that it can simultaneously crush the waste wires without prior sorting, achieving efficient separation and recycling of metals and plastics.
II. Application Scenarios
Wire waste sorting machines are widely used in industries such as electronic waste recycling and waste cable processing. It not only solves the problem of processing waste wires and cables but also allows the separated copper and plastics to be reused as important industrial raw materials in production, forming a closed loop of resource recycling.
III. Working Principle Of Wire Waste Sorting Machine
Wire waste sorting is mainly based on dry physical separation methods, combined with multiple technical processes.
1. Crushing and Pulverizing
The equipment first uses a multi-stage crushing system to break down the entire wire or cable into fine particles. Primary crushing typically involves tearing materials into pieces approximately 3cm in length, followed by further fine crushing in a secondary pulverizer. This process prepares the material for subsequent separation steps.
2. Sorting Technologies
Gravity Separation: Utilizing the density difference between copper and plastic, under the influence of wind and screen vibration, denser copper wires move along the screen surface towards the copper outlet, while less dense plastic floats above them towards the plastic outlet. The separation efficiency of this method is directly proportional to the diameter of a single copper wire; a larger diameter wire results in better separation.
Airflow Separation Technology: By controlling the airflow velocity, lighter plastic particles are separated from heavier metal particles.
High-Voltage Electrostatic Separation: Some advanced equipment is also equipped with an electrostatic separation system, utilizing the different behaviors of metals and non-metals in an electric field for secondary separation, which can further improve the separation rate.
3. Dust Removal and Environmental Protection
Modern sorting machines are equipped with multi-stage dust removal systems, typically including cyclone dust collectors, bag filters, and air purifiers, effectively controlling dust overflow with a dust removal efficiency of over 99%, avoiding secondary pollution.

With the increasing demand for resource recycling and increasingly stringent environmental requirements, wire waste sorting technology is developing towards higher efficiency, greater intelligence, and more environmental protection, playing an increasingly important role in the circular economy.
Through technological innovation and industrial application, wire waste sorting machines are quietly driving a green transformation in the electronic waste treatment industry, making resource recycling more efficient and environmentally friendly.
