What are Metal Shredders and how do they work?

To turn scrap metal into reusable materials, it first undergoes a series of processes. At Morecambe Metals, we utilize a variety of industrial metal processing tools, including metal shredders. These shredders allow us to handle an extensive array of both ferrous and non-ferrous metals on-site, prepping them for exportation to steel mills to be recycled into new metal products. Additionally, our shredders enable us to completely destroy materials when required by certain industries. Let's delve into what metal shredders are and how they function.

How Do Scrap Metal Shredders Operate?

Scrap metal shredders are designed to downsize scrap metal into transportable and manageable pieces. They come in various sizes; small units for shredding metals like tin cans and coins, to massive machines capable of demolishing 4,000 tons of metal daily, driven by engines up to 10,000 horsepower. These larger shredders work on materials such as end-of-life vehicles, bulk drums, and virtually every type of scrap metal.

The cutting mechanisms in shredders can vary: horizontal or vertical shafts, and configurations with single, double, or even multiple shafts. These shafts are equipped with blades that have claws of different thicknesses, tailored to the material being shredded. Shredders can also operate at varying speeds—high, medium, or slow. Typically, slow-speed, high-torque shredders are used in scrap metal recycling due to their capacity to effectively handle large metal pieces.

On an industrial level, large chunks of scrap metal, like crushed old cars, are fed into the shredder through a feeder pipe toward the shredding section, where robust hammers break the metal down. Magnets then separate ferrous from non-ferrous materials. Conveyor belts transport these separated materials to be further sorted into individual piles.

Morecambe Metals employs enormous shredders in its operations. Watch the video below to get a better idea of the scale of industrial scrap metal shredding:

 

Why Is Shredding Scrap Metal Necessary?

Transporting bulky scrap metal in its original state is impractical. For instance, an old vehicle takes up significant space, but once it’s crushed and shredded, it becomes much easier to handle. Shredding significantly reduces the volume of scrap metal, making it more manageable.

The shredding process also facilitates the separation of ferrous from non-ferrous metals, as well as other materials like rubber, plastics, and fabrics. As shown in the video, the shredder extracts magnetic metals from non-magnetic ones, maximizing the value derived from the scrap metal recycling process.

 

What Becomes of Shredded Scrap Metal?

Once shredded, metals are easily transported for further processing. Non-ferrous materials such as plastics, foam, glass, and textiles are extracted and routed for recycling, helping divert these items from landfills.

The shredded ferrous metals are shipped to facilities where they are melted down in large furnaces, commonly exported to steel mills worldwide that can efficiently process the material. At Morecambe Metals, we collaborate with local ports to export scrap metal globally, underscoring the extensive reach of our recycling services.

The molten metal undergoes purification to ensure it's free of contaminants, often achieved through electrolysis—a process that uses a direct electrical current to drive a non-spontaneous chemical reaction. The purified metal then cools and solidifies, ready to be used as raw material in manufacturing new products.

The Role of Metal Shredders in a Circular Economy

Industrial metal shredders, especially those used by companies such as ours, play a significant environmental role. Without these shredders, processing substantial volumes of bulky scrap metal efficiently would be impossible, affecting our ability to meet the global demand for recycled metal.

Currently, up to 40% of new metal is made from recycled materials, and increasing this percentage is vital to conserving the earth's natural resources. Shredding not only helps separate non-metal and non-ferrous materials from scrap metal but also diverts these materials away from landfills.

Understanding Double Shaft Industrial Metal Shredder Machines

With an improvement in living standards, the generation of domestic waste has surged. Dual-shaft shredders have simplified the management of such waste.

Commonly known as dual-shaft crusher machines, these shredders feature low-speed, high-torque blades. Structurally, two sets of main shafts with blades move in relative motion, squeezing and crushing the materials.

They are frequently utilized in environmental protection fields, including domestic waste disposal, resource regeneration, and fixed waste pre-treatment. These machines can crush waste metals, plastics, and wood efficiently, proving crucial for environmental management.

Equipped with a powerful reducer, industrial shredder machines boast a high torque cutting technique that meets diverse shredding needs. Materials difficult to break can be easily processed, ensuring safe investment in raw materials. The metal shredder machine increases the relative density of the material while reducing impurities, making it an ideal solution for waste treatment.
