Faced with the growing demand for processing waste motor rotors (containing high-value metals such as iron, copper, and aluminum), European customers are in urgent need of an efficient, automated solution that complies with EU environmental standards.

We designed and delivered a set of integrated waste rotor crushing and sorting system for it. The core configuration includes:

1. 2 heavy-duty crushers: heavy hammer crushing is used to ensure that the rotor is completely dissociated into a uniform mixture, improving the efficiency of subsequent sorting.

2. Double sets of multi-layer magnetic separators: multi-gradient magnetic field design, accurate separation of ferromagnetic materials (recovery rate> 99.9%), suitable for materials of different particle sizes.

3. Eddy current separator: eddy current separator is used to efficiently separate non-ferrous metals (copper and aluminum), ensuring that the purity of copper and aluminum reaches more than 99% respectively, solving the problem of light metal mixing.

4. Dust removal system: The whole process is closed crushing and sorting process, with dust removal system filtration, and the dust collection efficiency is> 99.5%.

Results and Value

Efficiency Leap: The system processing capacity reaches 8-10 tons/hour, which is 300% higher than the customer's original capacity, and the annual processing capacity is expected to exceed 50,000 tons.

High-value resources: The comprehensive recovery rate of iron, copper and aluminum exceeds 99%, and the metal purity meets the requirements of direct smelting.

Green compliance: The full closed design + dust collection system achieves nearly zero emissions, helping customers pass the EU WEEE directive certification. No wastewater is generated during the crushing and sorting process.

Low operation and maintenance costs:

The dust removal system automatically cleans the dust, and the filter bag life is extended to 18 months;

The whole system is automatically controlled, reducing 70% of manual intervention.

Customer evaluation

This system is far beyond expectations! The smooth connection from crushing to sorting has greatly increased our production capacity, and the metal purity has opened up the high-end recycling market. The dust removal effect is amazing-the air cleanliness in the workshop is even better than before the transformation!
