Metal Crusher Machine

Metal crusher machine is a high-efficiency machine specially designed for scrap metal crushing and recycling. It is widely used in various metal recovery applications and steel plant auxiliary production lines. The machine can operate independently or be combined with a metal shredder, eddy current separator, and scrap metal polisher to form a complete metal crushing and sorting line, meeting different capacity and output size requirements.

Materials Processed by the Metal Crusher

This scrap metal crusher machine can process more than 200 types of metal materials, suitable for various scrap sources:

1) Automobile and Vehicle Scrap

• Flattened car bodies
• Dismantled vehicle components
• Scrap motorcycle, electric bike, and bicycle frame parts

2) Light and Thin Metal Materials

• Sheared or baled light scrap with a density not exceeding 1 t/m³
• Color-coated steel sheets and light steel structures

3) Household Appliance Scrap

• Used washing machines
• Refrigerators
• Air conditioner shells and structural metal parts

4) Packaging and Aluminum Scrap

• Used aluminum cans (thin materials are crushed into small spherical particles)
• Paint buckets
• Scrap aluminum products

5) Common Scrap Steel and Iron

• Scrap sheet metal
• Scrap steel and iron
• Old metal materials
• Thermal break aluminum doors and windows
• Radiators and other metal components

For thin materials such as aluminum cans, the output is typically small spherical particles. For thicker materials, the crushed output is usually in flakes or small block shapes.

Metal Crusher Machine Structure and Working Principle

Reinforced Machine Body

The metal scrap crusher body is constructed with extra-thick steel plates and reinforced with diagonal supports, ensuring stable operation under heavy-duty crushing conditions. It is suitable for continuous large-scale scrap metal processing.

Hammer-Type Crushing Method

The equipment adopts a hammering crushing principle:

• Liners and hammers are made of high-strength manganese steel
• Improved wear resistance and longer hammer service life
• Strong crushing power

The hammers are installed in a movable structure. When uncrushable materials enter the crushing chamber, the hammers can swing away flexibly, allowing the foreign materials to be discharged through a dedicated outlet. This design helps reduce machine damage and improves operational safety.

Output Size and Configuration of The Metal Crusher Machine

After crushing, the material is discharged in spherical or granular form. The standard output size ranges from 3–10 mm.

The discharge size can be customized according to specific production requirements, making the machine suitable for different downstream sorting or smelting processes.

Conveying devices can be installed at both the feeding and discharge ends to ensure continuous and smooth material flow, making the system suitable for large-scale scrap metal recycling operations.

Applications of the Metal Crusher Machine

This metal crusher machine is widely used in:

• Scrap metal recycling and processing plants
• Waste metal treatment centers
• Steel mill auxiliary enterprises
• Scrap metal recovery companies

Whether used as a standalone machine or integrated into a complete aluminum thermal break recycling line, the metal crusher serves as a key piece of equipment in the metal recycling process.

Thermal Break Aluminum Recycling Line

For customers processing thermal break aluminum profiles and window frames, the metal crusher machine can be integrated into a dedicated recycling line. The typical configuration includes a dual-shaft shredder for primary size reduction, followed by the metal crusher for secondary crushing, and an Eddy Current Separator for efficient separation of aluminum and non-metallic materials. A Rotary Drum Polishing Machine can be added as an optional unit to further clean and polish the aluminum fraction, improving material purity and market value.

This configuration is suitable for recycling thermal break aluminum doors, windows, and mixed aluminum scrap, providing an efficient and practical solution for aluminum recovery.
