Pressed metal blocks are widely seen in scrap yards, metal recycling plants, steel mills, aluminum recycling workshops and material collection stations. These blocks are usually made from compressed scrap steel, scrap iron, aluminum scrap, sheet metal offcuts, light metal waste or mixed metal materials. They are pressed into compact shapes to save storage space and reduce transportation costs.
Common pressed metal materials include compressed metal blocks, metal briquettes, pressed scrap blocks, scrap steel blocks, aluminum blocks, iron blocks, pressed sheet metal blocks and mixed metal cubes. Compared with loose scrap metal, pressed metal blocks are much denser and harder to feed directly into a crusher. If the block is too large or too compact, direct crushing may increase machine load, reduce efficiency and cause unstable operation.
Haoxing Machinery provides practical shredding and crushing solutions for pressed metal blocks. According to the size, density and material composition of the blocks, we can configure a heavy-duty twin shaft shredder for primary breaking, followed by a scrap metal crusher for further crushing and densification. Magnetic separators, eddy current separators, conveyors and dust collection systems can also be added to build a complete recycling line.

How to Process Pressed Metal Blocks?
Pressed metal blocks are usually compact and heavy. For small and loose blocks, a metal crusher may be used directly depending on the machine model and feeding size. For large, dense or mixed metal blocks, Haoxing engineers usually recommend using a twin shaft shredder as the first step.
The shredder breaks the pressed blocks into smaller pieces through low-speed and high-torque cutting. This pre-treatment reduces the pressure on the downstream crusher and makes the feeding process more stable. After shredding, the material enters the metal crusher for further size reduction. The crushed output can then be separated by magnetic separators or eddy current separators according to the material type.
Typical Pressed Metal Block Recycling Process
The recycling process depends on block size, density and material composition. A typical processing line may include:
Pressed Metal Blocks → Feeding Conveyor → Twin Shaft Shredder → Scrap Metal Crusher → Magnetic Separator → Eddy Current Separator → Finished Metal Product
For scrap steel blocks, compressed scrap metal and mixed metal briquettes, pre-shredding is usually recommended before crushing. This ensures stable feeding and improves the overall efficiency of the recycling line.
Recommended Equipment Configuration
Loading or feeding conveyor
Heavy-duty twin shaft shredder for primary block breaking
Scrap metal crusher for secondary crushing
Magnetic separator for ferrous metal separation
Eddy current separator for aluminum and non-ferrous metal recovery
Belt conveyor for material transfer
Dust collection system for cleaner operation
Electric control cabinet for automatic line control
Why Shred Pressed Metal Blocks Before Crushing?
Pressed metal blocks are different from ordinary loose scrap. Their structure is compact, and the material inside may include different metals or irregular pieces. If the material is fed directly into the crusher without pre-treatment, the crusher may face sudden impact loads and uneven feeding conditions.
A twin shaft shredder can open and break the blocks first. This makes the material easier to crush, reduces the risk of blockages, protects crusher rotors and hammers, and improves the continuous working stability of the entire recycling line.
For customers processing large quantities of compressed scrap metal every day, this configuration is normally more efficient and more reliable.
Pressed Steel Blocks vs Loose Scrap Metal
Compared with loose scrap metal, pressed steel blocks occupy less storage space and are easier to transport over long distances. However, the compact structure of the material also increases the difficulty of direct crushing.
Loose scrap can often be fed directly into a crusher, while compressed scrap steel and briquetted metals generally require pre-shredding to achieve optimal crushing performance.
By combining a twin shaft shredder and a scrap metal crusher, recycling plants can achieve more stable operation, reduced wear and higher processing efficiency.

Equipment Selection Guide
The correct recycling solution depends on material type. Light steel briquettes, aluminum briquettes, cast aluminum blocks and mixed metal cubes may require different equipment configurations.
Factors such as block dimensions, bulk density, metal composition, throughput requirements and final output size should be considered before selecting shredder and crusher models.
Haoxing Machinery can design customized recycling systems for steel briquettes, aluminum briquettes, compressed scrap metal, pressed scrap steel and mixed metal blocks according to your actual material conditions.
Custom Solution for Your Pressed Metal Blocks
Different pressed metal blocks require different equipment configurations. A block made from light sheet metal is different from a block made from thick steel scrap or cast aluminum. The machine model should be selected according to the block size, density, metal type, feeding method, required capacity and final output requirement.
Haoxing Machinery can provide single machines or complete recycling lines for pressed metal blocks. You can send us photos, videos, block size, approximate weight and required capacity. Our engineers will recommend a suitable shredder, metal crusher, separator and conveyor system according to your actual material.
FAQ About Pressed Metal Blocks Processing
Can pressed metal blocks be crushed directly?
It depends on the block size, density and material type. Small and loose blocks may be crushed directly by a suitable metal crusher. For large or dense pressed blocks, a twin shaft shredder is recommended before crushing.
What machine is suitable for pressed metal blocks?
A heavy-duty twin shaft shredder is commonly used for primary breaking of pressed metal blocks. After shredding, a scrap metal crusher can be used for further crushing and material densification.
Can one line process both steel blocks and aluminum blocks?
In many cases, one recycling line can process different metal blocks, but the machine configuration should be adjusted according to material hardness, block size and final separation requirements.
Can the system separate iron and aluminum after crushing?
Yes. A magnetic separator can separate ferrous metals after crushing. If the material contains aluminum, copper or other non-ferrous metals, an eddy current separator can be added for further recovery.
What information should I provide for equipment selection?
You can provide material photos or videos, block size, approximate block weight, main metal type, required capacity and final output requirement. Based on this information, Haoxing Machinery can design a suitable processing solution.
What is the difference between metal briquettes and scrap metal bales?
Metal briquettes are usually high-density compressed metal blocks produced by briquetting machines, while scrap metal bales are large compressed packages made by balers. Both materials often require pre-shredding before further crushing and separation.
Can aluminum briquettes and steel briquettes be processed on the same system?
Yes. In many recycling plants, a properly configured recycling line can process both aluminum briquettes and steel briquettes. Equipment selection should be based on material hardness, density and required output specifications.
