Line for recycling aluminium wire with a steel core

During power line renewal projects, substantial quantities of aluminium-clad steel core (ACSR) cables are replaced. These cables comprise an outer aluminium conductor stranded around an internal steel core, offering a compact structure and high strength. Traditional cutting methods for separation prove inefficient and result in significant metal loss. Addressing these material characteristics, specialised aluminium-steel separation recycling lines have emerged to achieve efficient, stable metal separation operations.

Crushing and Pre-processing System

The entire recycling line commences with a cutting machine, which segments the lengthy cables into manageable lengths. These then proceed to specialised crushing or stripping equipment. Featuring high-strength blades and wear-resistant structural design, this apparatus effectively breaks the stranded structure between the aluminium layer and steel core. The primary objective at this stage is to loosen the intertwined metals, preparing them for subsequent separation while preserving particle integrity to minimise pulverisation losses.

Core Technology of ACSR Separation Equipment

The heart of the recycling line is the dedicated ACSR separator. This equipment progressively separates the aluminium conductor from the internal steel core through principles of compression, rolling, and mechanical stripping. The separation process requires no chemical treatment, relying entirely on physical methods—ensuring both environmental safety and operational security.

The equipment can adjust roller gaps and pressure parameters to accommodate cables of varying specifications, adapting to multiple diameters and structural configurations. Following separation, the aluminium wire and steel core are discharged through distinct outlets, achieving high purity suitable for direct re-melting or reprocessing. Automated feeding and continuous operation design significantly enhance overall processing efficiency, making it ideal for large-scale recycling operations.

Automated Control and Stable Operation

The entire production line is equipped with a PLC control system, centrally managing cutting, crushing, and separation processes. The user interface is simple and intuitive, with flexible adjustment of operational parameters. The robust frame structure and protective devices ensure long-term stable operation under high-load conditions while reducing maintenance costs.

Through specialised aluminium-steel separation production lines, aluminium and steel from ACSR cables can be efficiently recovered and reused. For enterprises engaged in power material recycling, introducing mature and reliable equipment represents a crucial step towards enhancing resource utilisation and economic benefits.
