Aluminum Can Shredder Aluminum Turnings Shredder Scrap Metal Shredder For Recycling Plant

Aluminum can shredder is a mechanical device specifically designed to shred aluminum cans (such as beverage cans and food cans) and is considered a metal recycling pre-processing device. Its core function is to break whole aluminum cans into small pieces or granules (typically 5-20mm in size) through mechanical shearing and extrusion. This facilitates subsequent recycling processes like sorting and smelting, significantly improving the efficiency and cost-effectiveness of aluminum resource recovery.

Operating Principle
The aluminum can shredder's operating principle is based on a combination of shearing and extrusion. The specific process is as follows:

1. Feeding Stage: Aluminum cans are fed into the shredder's feed port via a conveyor belt or manually. The shredder is typically equipped with safety features (such as an emergency stop button and anti-jamming design) to ensure safe operation.

2. Crushing Stage:

• Shearing Blade: The shredder is equipped with a rotating rotor blade and a fixed static blade (mostly made of high-hardness alloy steel). Once the aluminum can enters the crushing chamber, the high-speed rotation of the rotor blade creates a shear force against the static blade, tearing the can's metal shell apart.

• Extrusion Crushing: Some models are equipped with rollers or impact plates, which simultaneously apply pressure to the aluminum can while shearing, further damaging its structural integrity, particularly at the can's seams (such as the "ring weld" on soda cans) and the raised bottom portion.

3. Discharge Stage: Crushed aluminum blocks are discharged through a screen (adjustable aperture). Larger particles that do not meet the required particle size remain in the crushing chamber and continue to be crushed until they meet the required particle size.

Core Advantages

1. Efficient Pre-Processing: The entire can is directly crushed into smaller pieces, reducing its volume by 80%-90%, significantly reducing subsequent transportation and storage costs.

2. Improved Sorting Purity: After crushing, aluminum ingots are more easily processed through processes such as magnetic separation (to separate residual iron impurities) and eddy current separation (to separate non-metallic materials such as plastic labels), increasing the purity of recycled aluminum (to over 98%).

3. Reduced Melting Energy Consumption: Smaller aluminum ingots have a larger surface area, allowing for more even heating in the furnace and faster melting (reducing energy consumption by approximately 20%-30%), while also reducing metal burn during the melting process.

4. High Adaptability: The system can process aluminum cans of varying sizes (including coated and printed cans) and maintains consistent crushing performance for thin metals (e.g., cans with a wall thickness of 0.1-0.2mm).
