Scrap aluminum wire recycling machine

Introduction:

Scrap aluminum wire recycling machine can be used to separate High-quality alu granules and insulated wire scrap for recycling Scrap aluminum wire, it can also process copper cable.

How to work:

Recycling of waste aluminum wire involves a systematic, multi-step process designed to maximize metal recovery while ensuring environmental sustainability:

Step 1: Initial Crushing & Iron Removal

Waste aluminum wire is first subjected to rough crushing to break down bulk materials. During this stage, iron-containing impurities are extracted using magnetic separation, ensuring the feedstock is free from ferrous contaminants that could hinder subsequent processing.

Step 2: Fine Crushing & Homogenization

The de-ironed material undergoes secondary crushing to produce a uniform mixture of metal (aluminum) and plastic. This step ensures particle size consistency, a critical factor for efficient separation in downstream processes.

Step 3: Gravity Separation

Leveraging the significant density difference between aluminum (metal) and plastic, the homogeneous mixture is processed through a gravity separator. This technology efficiently segregates the two components, with aluminum settling out due to its higher weight, while plastic particles are separated as lighter fractions.

Step 4: Electrostatic Refining

While gravity separation removes most plastic, residual aluminum fines or filaments (typically 2–5% of the plastic fraction) may remain. An electrostatic separator is employed to recover these minute aluminum particles. By utilizing differences in electrical conductivity, aluminum—being conductive—is separated from non-conductive plastic, ensuring near-complete metal retrieval.

The result is a high-purity aluminum product and plastic fraction free of metallic residues, significantly enhancing the value of both recycled materials.
