Aluminum Can Recycling Equipment: Complete Processing Guide 2024

Aluminum can recycling represents one of the most economically and environmentally compelling sectors in the waste processing industry. With aluminum retaining 100% of its properties through infinite recycling cycles and using just 5% of the energy required for primary production, used beverage cans (UBCs) are among the most valuable recyclable materials available. Investing in the right aluminum can recycling equipment directly determines operational efficiency and profitability.

LVKESORT has engineered aluminum can processing solutions for recycling facilities across 40+ countries. This comprehensive guide examines the complete equipment chain required for profitable aluminum can recycling, from bale breaking to final melting preparation.

The Aluminum Can Recycling Process Overview

Modern aluminum can recycling involves a carefully orchestrated sequence of processing steps designed to maximize material recovery while minimizing energy consumption and operating costs. Each stage requires specialized equipment calibrated to the unique properties of aluminum beverage containers.

A complete aluminum can recycling line typically follows this processing sequence:

1. Bale Breaking / Debaling – Opening compressed bales of collected UBCs
2. Magnetic Separation – Removing steel cans and ferrous contaminants
3. Shredding / Granulation – Reducing cans to uniform particle size
4. Air Classification – Removing paper, plastic labels, and light contaminants
5. Optical Sorting – Separating aluminum from other non-ferrous metals
6. De-coating / Delacquering – Removing paint and coatings before melting
7. Densification / Baling – Compacting clean aluminum for transport

Essential Aluminum Can Recycling Equipment

Can Shredders and Granulators

The shredding stage serves as the foundation of any aluminum can recycling operation. LVKESORT's D-series single shaft shredders and PS-series crushers deliver controlled size reduction that prepares cans for downstream separation processes. For aluminum can processing, shredder blade geometry and screen size are critical parameters that affect both throughput and downstream separation efficiency.

Single shaft shredders from LVKESORT, such as the D160 model, excel at processing baled UBCs, producing uniformly shredded pieces typically between 20-50mm in size. This particle size optimizes subsequent air classification and magnetic separation performance while avoiding the excessive fines generation that reduces yield.

Processing Capacity: 500 kg/hr to 5,000 kg/hr depending on machine size and configuration

Eddy Current Separators

While magnetic separation handles ferrous metal removal, eddy current separators provide the critical function of extracting non-ferrous aluminum from mixed waste streams. These separators use powerful rotating magnetic fields to repel aluminum particles, launching them off the conveyor belt trajectory into a separate collection chamber.

LVKESORT's eddy current separators achieve 98%+ aluminum recovery rates from mixed beverage can streams, even when processing heavily contaminated input material. The high-frequency rotor design creates sufficient repulsion force to separate even thin aluminum foil fragments and crushed can bodies.

Air Classification Systems

Air separators remove the paper labels, plastic liners, and other lightweight contaminants that inevitably accompany collected aluminum cans. These systems use controlled airflow to lift lighter materials while allowing denser aluminum pieces to fall through the airstream into a separate output stream.

Effective air classification is essential because residual paper and plastic cause significant problems in downstream melting operations, including dross formation and metal loss. LVKESORT integrates multi-stage air classification into its can recycling lines to ensure output purity exceeding 99%.

Optical Sorting Technology

For operations requiring the highest purity aluminum output, optical sorting systems provide an additional quality control layer. Using near-infrared (NIR) spectroscopy, these sorters identify and eject non-aluminum materials, including other non-ferrous metals that might pass through eddy current separation.

While not always necessary for dedicated UBC processing, optical sorting becomes valuable when processing mixed container streams containing aluminum cans, steel cans, plastic bottles, and glass containers in a single feed.

Equipment Configuration by Operation Scale

Operation Scale	Monthly Volume	Key Equipment	Estimated Investment	Typical Recovery Rate
Small Scale	50-200 tons	Small shredder, magnetic separator, basic air classifier	$35,000 - $80,000	90-95%
Medium Scale	200-1,000 tons	Medium shredder, eddy current separator, multi-stage air system	$80,000 - $250,000	95-98%
Large Scale	1,000-5,000 tons	Primary + secondary shredder, eddy current, optical sorter, de-coating	$250,000 - $800,000+	98-99.5%
Industrial Scale	5,000+ tons	Full processing line with automation, multiple sorting stages	$800,000 - $2,000,000+	99%+

Key Considerations for Equipment Selection

Input Material Characteristics

The source and condition of your incoming aluminum cans significantly influence equipment requirements. Curbside-collected UBCs arrive in highly contaminated bales containing steel cans, plastic bottles, glass, paper, and general trash. In contrast, deposit-return system cans arrive much cleaner, requiring fewer separation stages.

Operations processing mixed municipal recyclables need more robust sorting equipment including multiple magnetic separators, eddy current units, and potentially optical sorting. Facilities receiving pre-separated UBC bales can often operate with simpler equipment configurations and achieve higher throughput per dollar invested.

Output Purity Requirements

Aluminum buyers pay premium prices for cleaner material, making output purity a direct driver of revenue. Can smelters typically specify 98% minimum purity, with the highest pricing available at 99%+ purity levels. Each additional piece of sorting equipment incrementally improves purity but adds capital cost and energy consumption.

LVKESORT engineers help clients determine the optimal purity target by analyzing local market pricing, contaminant levels in incoming material, and equipment costs to identify the point where additional purification costs exceed the revenue premium generated.

Energy Efficiency and Operating Costs

Energy consumption represents one of the largest ongoing operational expenses in aluminum can recycling. LVKESORT equipment designs emphasize energy efficiency through optimized rotor geometry, high-efficiency motor configurations, and variable frequency drive systems that adjust power consumption based on actual processing load.

Modern shredder designs can reduce specific energy consumption by 20-30% compared to older equipment, with savings that quickly accumulate when processing thousands of tons annually. Selecting the correct machine size for your actual throughput requirements is perhaps the most important factor in minimizing energy costs.

Maintenance Requirements for Can Recycling Equipment

Aluminum is a relatively soft metal, meaning can recycling equipment experiences less abrasive wear than systems processing glass or construction debris. However, proper maintenance remains essential for consistent performance and longevity.

Critical maintenance areas include:

• Shredder Blade Inspection: Regular sharpening or rotation schedules based on throughput
• Bearing Lubrication: High-temperature bearings in shredders and eddy current rotors require scheduled lubrication
• Belt Tension and Condition: Conveyor and drive belts need periodic adjustment and replacement
• Magnet Strength Verification: Periodic testing of magnetic separator performance
• Air System Filter Changes: Dust collection and air classification filters need regular replacement
