Detailed Overview of ACSR Recycling Equipment & Steel-Core Aluminum Separation

As demand for overhead conductor recycling continues to grow, processing discarded ACSR cable has become an increasingly important segment of industrial metal recovery. Unlike ordinary scrap wire, Aluminum Conductor Steel Reinforced (ACSR) cable combines outer aluminum strands with a high-strength steel core, creating a composite structure that is difficult to separate using standard wire granulation systems. This is why a dedicated ACSR recycling machine is required to achieve stable output and high recovery value.

The recycling process begins with controlled cutting. A specialized ACSR shredder or cutting unit reduces long conductors into short sections, typically 3–5 cm in length, using low-speed, high-torque blades designed to handle steel-reinforced cable without excessive wear. Uniform cutting is critical because stable particle size directly improves downstream separation accuracy. Modern systems also support multi-strand feeding, allowing several cables to enter simultaneously and increasing productivity for industrial recyclers handling large volumes of overhead conductor scrap.

Once cut, the material enters the most important stage: magnetic separation. A powerful steel-core aluminum separator utilizes magnetic force to extract the ferrous core from the non-magnetic aluminum fraction. Belt-type magnetic separators or magnetic drums are commonly used because they deliver continuous steel discharge with high reliability. For operations requiring higher aluminum purity, an eddy current separator can be added to remove remaining non-metallic residues and enhance final aluminum cleanliness, with optimized systems achieving separation rates of nearly 99%.

To ensure clean production, the complete ACSR recycling equipment is usually equipped with a pulse dust collection system or bag-type dust filter, reducing airborne particles generated during cutting and conveying. Compared with manual dismantling or conventional cable recycling methods, this integrated approach offers lower labor demand, more stable recovery efficiency, and stronger economic returns. For recyclers investing in overhead conductor recycling, a dedicated steel and aluminum separation line remains the most practical solution for producing high-purity secondary metal from special cable waste.
