Scrap metal shredder

Scrap metal shredders are key equipment in the metal recycling industry, specifically used to crush various types of scrap metals, such as car shells, home appliances, scrap steel, aluminum cans, etc., into uniform fragments that can be melted. This equipment not only improves the efficiency of metal recycling, but also greatly reduces transportation and smelting costs, playing an important role in the field of resource recycling.

Equipment structure and working principle

Scrap metal shredders usually adopt a dual-axis or multi-disc design, and break metal materials into small pieces through the shearing and extrusion of high-strength alloy cutters. Its core advantages include:

High torque power system: can handle heavy metals such as car frames or industrial waste;

Intelligent overload protection: can automatically reverse when encountering hard objects to avoid equipment damage;

Modular cutters: easy to replace to meet different metal crushing needs.

Scrap metal recycling process

Pretreatment: Separate ferrous metals through magnetic separators to remove impurities such as plastics and rubber;

Shredding and crushing: Scrap metal enters the shredder and is broken into 50-100mm fragments;

Sorting and purification: Eddy current separators separate non-ferrous metals (such as copper and aluminum);

Smelting and regeneration: Pure metal fragments are sent to smelters for recasting and become new raw materials.

Economic and environmental benefits

Reduce smelting energy consumption: Crushed metal saves 20%-30% energy compared to melting a whole piece of scrap;

Reduce transportation costs: Shredding and compression reduce the volume of metal by more than 50%;

Promote circular economy: Each ton of recycled steel can reduce 1.5 tons of CO₂ emissions and save 1.4 tons of iron ore.

Industry application and development trend

Scrap metal shredders are widely used in the fields of scrap car dismantling, electronic waste recycling, and waste machinery processing. With the advancement of intelligent sorting technology and efficient energy-saving design, future equipment will develop in the direction of automation, low noise, and high production capacity, further promoting the sustainable use of global metal resources.

Scrap metal shredders are not only a powerful tool for the recycling industry, but also an important technical support for achieving the “dual carbon” goals, providing a solid foundation for the development of green industry.
