Applicable Materials: Prepared aluminum crankcases, engine housings, gearbox housings, transmission housings, cylinder blocks, compressor housings, motor housings and other cast aluminum automotive or machinery components. Feeding suitability depends on casting dimensions, wall thickness, internal steel parts and attached components.

The aluminum crankcase crusher is a hammer-type crushing machine used to process prepared aluminum crankcases, engine housings, gearbox housings, transmission housings, cylinder blocks and other cast aluminum automotive parts.
A high-speed rotor drives the hammers to repeatedly impact, deform and break the prepared castings inside the crushing chamber. The screen or grate helps control the discharge size, while the crushing action exposes embedded bolts, steel liners, shafts and other attached components for downstream separation.
Engine housings and crankcases that meet the crusher feeding limits may be processed directly. Oversized, unusually thick or irregular castings may require dismantling, hydraulic breaking or primary processing by a twin shaft shredder before entering the crusher.
After crushing, a magnetic separator can recover exposed iron and steel components from the aluminum-rich material stream. Additional screening or manual sorting may be required according to the construction and internal components of the incoming castings.
An eddy current separator may be added when conductive non-ferrous metals need to be recovered from a suitable non-metallic material stream. It does not normally separate mixed aluminum, copper and other non-ferrous metals into individual high-purity products.
The aluminum crankcase crusher can operate as an individual machine or as part of an aluminum recycling line with controlled feeding, material conveying, magnetic separation, optional sorting and dust collection. The final configuration depends on the casting dimensions, wall thickness, internal steel components, required capacity, expected output size and recovery objective.
Aluminum crankcases and engine housings should be drained and inspected before mechanical processing. Residual oil, coolant, sealed cavities and unsuitable attachments should be removed or handled according to local operating requirements.
Large steel shafts, bearings and easily removable components should be dismantled where practical. The selected crusher model must match the maximum casting dimensions, wall thickness and internal steel content.
Aluminum crankcases and cast aluminum parts are fed into the crushing chamber by conveyor or loader. The rotor drives high-strength hammers to rotate at high speed. The material is repeatedly impacted, torn, and crushed between the hammer, lining plate, and screen until it reaches the required size.
After crushing, a magnetic separator can recover exposed ferrous components such as bolts, steel inserts, liners and shaft fragments. The remaining material can then be screened or manually inspected according to the required recovered fractions.
An eddy current separator may be considered when the processed material contains conductive non-ferrous metals mixed with suitable non-metallic residues. Its suitability depends on particle size, material composition and feeding condition.
Targeted design for cast aluminum automotive parts and machine aluminum scrap.
Strong impact crushing force for thick engine housings and crankcase material.
Helps release embedded iron parts and improve downstream separation efficiency.
Screen aperture can be customized for different smelting and recycling requirements.
Wear-resistant hammers and liners reduce maintenance frequency for hard cast aluminum.

Note: Capacity varies with casting size, wall thickness, iron content, feeding continuity, and required discharge size.
Find common questions about scrap metal crushers, shredders, recycling lines, equipment selection, capacity configuration and operation requirements.
To recommend a suitable aluminum crankcase crusher, it is helpful to provide material photos or videos, crankcase size, material thickness, hourly capacity requirement, required final size, voltage, workshop layout, and whether you need conveyors or sorting equipment. With these details, the crusher model and full line configuration can be selected more accurately.
Before crushing, sealed containers, explosive materials, and highly flammable residues should be removed. Operators should also check whether the feeding size is suitable for the machine. Proper overload protection, emergency stop devices, dust control, and regular maintenance can help improve safety during operation.
Maintenance frequency depends on the working hours, material hardness, feeding size, and impurity content. Aluminum itself is relatively soft, but steel parts inside the crankcase can increase wear. Regular inspection of hammers, blades, liners, bearings, and screens is important to keep the crusher working efficiently.
Yes. A complete aluminum crankcase recycling line can include a feeding conveyor, crusher, discharge conveyor, magnetic separator, eddy current separator, dust collector, and control system. The exact configuration depends on the material condition and the required purity of the final aluminum scrap.
A feeding conveyor is recommended for stable and safe operation, especially when processing large quantities of crankcases. It helps control the feeding speed, reduce manual labor, and keep the crusher running continuously. For small batches, manual feeding may be possible, but mechanical feeding is better for long-term production.
The capacity varies according to the machine model and material condition. Small and medium models can meet general recycling needs, while larger industrial crushers can process several tons per hour. Clean aluminum crankcases are usually easier to crush, while materials mixed with steel parts or heavy castings may reduce the actual output.
The right model depends on the size of the crankcases, material thickness, feeding method, required capacity, final output size, and whether the material contains steel impurities. For small recycling yards, a medium-capacity crusher may be enough. For large-scale aluminum recycling plants, a heavy-duty model with stronger power and continuous feeding is recommended.
The final size depends on the crusher model, rotor design, screen opening, and customer requirements. In most recycling applications, aluminum crankcases are crushed into smaller, more uniform pieces for easier melting, separation, or storage. If you need a specific output size, the machine can be configured accordingly.
Yes, many aluminum crankcases may contain bolts, bearings, steel inserts, or other mixed metal parts. A properly configured crusher can handle this kind of mixed scrap, but the following sorting process is also important. A magnetic separator is often used after crushing to remove ferrous impurities from the aluminum material.
An aluminum crankcase crusher is used to crush waste aluminum engine crankcases, gearbox housings, motor housings, and other cast aluminum scrap into smaller pieces. It helps reduce material volume, improve transportation efficiency, and prepare the scrap for sorting, melting, or further recycling.
