Define the final fraction first. Build the line backwards.

Defective cast aluminum parts—such as engine blocks, transmission housings, and wheels—represent a high-value resource. However, their large size and embedded ferrous or non-ferrous inserts make direct re-melting inefficient. Our specialized processing systems are engineered to crush these bulky castings, liberate embedded contaminants, and deliver clean, high-purity aluminum scrap. Through a continuous, automated route, we help you maximize recovery rates and minimize downstream melting costs.

01

High-Purity Cast Aluminum

After crushing and separation, the aluminum fraction is clean, uniform, and free of embedded contaminants. This high-purity scrap is ideal for direct re-melting, significantly reducing energy consumption and refining costs.

Aluminum
02

Recovered Steel & Iron

Ferrous inserts such as steel bolts, bearings, and iron sleeves are efficiently extracted using strong magnetic separators. The recovered iron and steel are clean and ready for direct smelting.

Ferrous
03

Non-Ferrous Inserts & Fines

Non-ferrous inserts like copper wires and brass fittings are separated using eddy current separators. The remaining dust and fines are collected for safe disposal or further processing.

Typical process architecture

One continuous route from bulky aluminum castings to separated output.

01

Heavy-Duty Feeding

Bulky cast aluminum parts are loaded into the system via grab cranes or heavy-duty chain conveyors. The feeding process is precisely controlled to ensure a steady and continuous flow into the shredder.

02

High-Torque Shredding

Equipped with robust, wear-resistant cutters, our twin-shaft shredders aggressively crush large castings into uniform, manageable pieces. This step effectively liberates embedded steel and copper inserts from the aluminum matrix.

03

Final Handling & Recovery

The separated high-purity aluminum fraction is transported to storage or baling stations. Clean ferrous and non-ferrous metals are stockpiled for recycling, while dust and fines are collected for safe disposal.

Frequently asked questions

Clarify the project before defining equipment.

What should I confirm about Aluminum castings?

Confirm casting dimensions, alloy, attached components and the receiving recovery process.

How is the equipment or process selected?

Selection considers material form and composition, required capacity, contamination, operating hours and the downstream result. A material review is needed before confirming a configuration.

Can the final output be specified?

Define the size or fraction required by the next process. Cutter geometry, any sizing or separation stages, feeding and material behavior must be considered together.

What information should I send first?

Send representative material photos, dimensions, hourly capacity, required output, site constraints and destination country.
