Bulky and irregular metal waste, large sheets, long profiles, components with complex shapes, are hard to feed directly and uniformly into a shredder. A metal waste shearing press solves this problem by pre-compressing and shearing the material into pieces of controlled size and shape, optimizing the feeding of the shredder and protecting it from overloading or from jams caused by bulky irregular parts.
A metal waste shearing press is a valuable pre-processing stage in metal recycling plants, especially for waste with difficult shapes. Compressing and shearing the material before shredding increases throughput, reduces shredder wear, and allows the processing of materials that would otherwise be problematic. See the full range of recycling equipment and the solutions for metal recovery.
Key Advantages for a Metal Shearing Press for Shredders
• Pre-compression and shearing, compresses and shears bulky material into pieces of controlled size.
• Uniform feeding of the shredder, the uniform pieces allow controlled feeding, without load peaks that overstress the shredder.
• Protection of the shredder, pre-processing protects the shredder from bulky irregular parts that could cause jams or wear.
• Increased throughput, controlled feeding allows the shredder to work at optimal capacity consistently.
• Processing of difficult shapes, large sheets, long profiles, and irregular components become processable after shearing.
• High hydraulic force, the hydraulic system develops the force needed to compress and shear the metals.
• Densification for transport, the compressed material has a higher density, reducing transport cost.
• PLC control, automated compression and shearing cycle.

Applications for Pre-Processing Bulky Metal Waste
A metal waste shearing press is used as a pre-processing stage in metal recycling plants that process bulky waste with difficult shapes: large steel sheets, long profiles, structural components, and irregular industrial metal waste. These materials, fed directly into a shredder, would cause load peaks, jams, or accelerated wear; pre-processing turns them into material that is easy to process.
Metal waste management is regulated at the European level; a metal waste shearing press delivered in Europe is designed in line with the requirements of Directive 2006/42/EC on machinery. For integration into a complete metal recycling flow, see also the complete industry solutions.
Protecting the shredder is the main benefit: the shredder is the most expensive piece of equipment in the plant, and feeding it bulky irregular parts accelerates its wear and risks jams. Pre-processing with shearing delivers uniform pieces of controlled size to the shredder, extending the lifespan of the components and reducing unscheduled stops.
Increasing the throughput of the entire plant is a direct effect of uniform feeding: when the shredder receives material of a consistent size and shape, it works at optimal capacity consistently, without load peaks that would slow or stop it. A press as a pre-processing stage allows the shredder to reach its nominal throughput, optimizing the capacity of the entire recycling flow.
High hydraulic force is needed to compress and shear the metals: thick sheets, steel profiles, and structural components offer high resistance. The hydraulic system develops the force needed to compress and shear these materials efficiently, turning them into processable pieces with a single stroke.
Densifying the material through compression has a secondary benefit for transport: bulky metal waste takes up a lot of space, and compressed material has a higher density. This reduces the transport cost per ton, both within the plant and when delivering to other processing facilities or smelters.
Processable Materials
| Material | Notes |
|---|---|
| Large steel sheets | Sheared into processable pieces |
| Metal profiles and beams | Long lengths reduced through shearing |
| Structural components | Irregular shapes compressed |
| Industrial metal waste | Bulky, from demolition and production |
| Metal casings and containers | Compressed for uniform feeding |
How It Works
1. The bulky metal waste is fed into the chamber of the press.
2. The hydraulic system compresses the material, reducing its volume.
3. The shearing mechanism cuts the compressed material into pieces of controlled size.
4. The uniform pieces are discharged onto a conveyor toward the shredder.
5. The shredder receives uniform material, working at optimal capacity consistently.
6. The cycle repeats automatically, coordinated by the PLC system.
The PLC system coordinates the compression and shearing cycle. A correctly integrated metal waste shearing press optimizes the feeding of the shredder, increasing the throughput of the entire plant and protecting the costly equipment from wear and jams.
Frequently Asked Questions
Why do I need a shearing press before the shredder?
Bulky and irregular metal waste (large sheets, long profiles) fed directly into a shredder causes load peaks, jams, and accelerated wear. A shearing press compresses and shears them into uniform pieces, protecting the shredder and allowing it to work at optimal capacity consistently.
What force does the press develop?
The hydraulic force is sized according to the type and thickness of the materials processed. Thick sheets and steel profiles require a high force for compression and shearing. The exact force is configured according to the specifics of the metal waste processed in your plant.
Does it effectively increase the plant's throughput?
Yes. Through the uniform feeding of the shredder, the press allows the shredder to work at optimal capacity consistently, without load peaks that would slow it down. This increases the effective throughput of the entire recycling flow and optimizes the use of the shredder's capacity.
Can it also be used independently of the shredder?
Yes. A metal waste shearing press can also be used to densify metal waste for transport, independently of the shredder. Compression reduces the volume and the transport cost. However, the main benefit is as a pre-processing stage that optimizes the feeding of the shredder in the recycling flow.
