Alva Machinery Group, a leading global manufacturer of comprehensive recycling equipment, today announced its participation in ALUMINIUM CHINA 2026, Asia's premier trade exhibition for the aluminum industry. The company will present its full-spectrum aluminum scrap crushing and recycling production line at Booth 5F15, Hall N5, Shanghai New International Expo Centre (SNIEC), from July 8 to 10, 2026.
As the 21st edition of this landmark industry event, ALUMINIUM CHINA 2026 gathers over 600 exhibitors and 25,000 industry professionals across 45,000 square meters of exhibition space, covering the entire aluminum value chain from primary production and recycled aluminum to downstream applications in automotive, construction, packaging, and renewable energy sectors. For Alva Machinery Group, the exhibition serves as a strategic platform to demonstrate its engineering expertise in scrap metal processing and connect with aluminum producers, recyclers, and downstream manufacturers worldwide.
"Against the global backdrop of carbon neutrality and circular economy goals, recycled aluminum has become the fastest-growing segment of the aluminum industry," said the Sales Director of Alva Machinery Group. "Producing one ton of recycled aluminum saves approximately 95% of the energy required for primary aluminum production, making it a cornerstone of the industry's low-carbon transition. Our aluminum scrap crushing and recycling line is engineered precisely to help our customers maximize metal recovery rates, minimize oxidation loss, and produce clean, furnace-ready aluminum scrap that meets the strictest smelter feedstock standards."
The global aluminum recycling sector is undergoing a profound structural upgrade. As environmental regulations tighten and smelters raise their feedstock quality requirements, crude manual sorting and simple crushing operations can no longer meet market demands. Impurities such as iron, plastic, rubber, and paint coatings not only reduce the quality of recycled aluminum ingots but also increase smelting energy consumption and pollutant emissions.
Iron contamination is particularly harmful. Excessive iron content forms brittle intermetallic compounds in aluminum alloys, degrading mechanical properties and corrosion resistance. Commercial aluminum alloys typically require iron content below 1.2%, making effective pre-smelting iron removal a critical quality control step.
Meanwhile, the feedstock landscape is becoming increasingly diverse. Modern recycling facilities must handle everything from thick aluminum extrusions and cast aluminum parts to thin aluminum cans, foil, aluminum-plastic composites, and end-of-life vehicle aluminum components. A one-size-fits-all crushing approach leads to high metal loss, inconsistent output size, and excessive fine powder generation that increases oxidation loss during melting.
This is where Alva Machinery Group's integrated aluminum scrap crushing and recycling production line delivers tangible value. By combining heavy-duty shredding, precision crushing, multi-stage magnetic separation, eddy current sorting, and intelligent dust collection into a single automated workflow, the system transforms raw, contaminated aluminum scrap into high-purity, uniformly sized feedstock ready for direct smelting.
The Alva aluminum scrap recycling line is a modular, fully integrated processing system configured according to each customer's feedstock type, throughput capacity, and final product specifications. A standard production line consists of six core processing stages, each engineered to perform a specific function in the value-upgrading process.
Raw material is loaded onto a heavy-duty apron conveyor or belt conveyor that delivers material at a controlled, uniform feed rate. The system features an adjustable speed drive matched to downstream crusher load, preventing jams and ensuring stable throughput. Before entering the primary shredder, operators can perform manual pre-sorting to remove obvious non-processable objects such as large steel blocks and stones, protecting downstream equipment.
For bulky materials such as aluminum extrusion offcuts, aluminum engine blocks, aluminum wheel rims, aluminum ladders, and compressed aluminum bales, a heavy-duty dual-shaft shredder performs the first size reduction stage. The shredder uses two counter-rotating shafts fitted with interlocking cutter blades that shear, tear, and cut material into pieces of approximately 100–200 mm.
Alva's shredders feature high-torque, low-speed design with hardened alloy steel cutters, delivering exceptional durability even when processing mixed scrap containing occasional steel fasteners and attachments. The low rotational speed minimizes dust generation and fine powder formation, reducing metal loss and improving workplace air quality.
After primary shredding, material is conveyed to a dedicated vertical aluminum crusher for secondary fine crushing. This is the core size-reduction stage that reduces material down to 10–50 mm according to customer requirements, creating dense, uniform granules with minimal dust.
Unlike general-purpose hammer crushers, Alva's aluminum-specific crusher is optimized for the ductile nature of aluminum. It features a combination of impact and shear crushing mechanisms that produce clean, cubical particles rather than elongated flakes or excessive fines. The interior lining is made of wear-resistant manganese steel, and the rotor assembly undergoes precision dynamic balancing to G2.5 standards for smooth, vibration-free operation.
An intelligent overload protection system automatically reverses and clears the chamber if uncrushable objects enter, preventing equipment damage and reducing downtime – a feature that significantly improves operational reliability for mixed scrap processing facilities.
Iron removal is arguably the most critical quality control step in aluminum scrap processing. Alva production lines deploy magnetic separation at multiple points throughout the process flow to ensure thorough iron removal.
First, a suspended permanent magnetic separator is installed above the conveyor after primary shredding to capture large ferrous pieces such as bolts, brackets, and steel attachments. Then, after secondary crushing, a drum-type magnetic separator performs finer iron removal, capturing even small iron particles and steel shavings. This staged approach achieves iron removal rates above 98%, ensuring the final aluminum product meets the strict purity requirements of premium smelters.
For feedstock containing mixed non-ferrous metals and non-metallic impurities – such as aluminum cans with plastic labels, aluminum radiator scrap with copper tubes, and municipal solid waste aluminum fractions – Alva integrates its high-performance eddy current separator into the processing line.
Utilizing high-intensity rare-earth magnetic rotors spinning at over 3,000 RPM, the separator generates a rapidly alternating magnetic field that induces eddy currents in non-ferrous metals, creating a repulsive Lorentz force that ejects aluminum and copper particles away from the material trajectory. This effectively separates non-ferrous metals from non-conductive materials like plastic, rubber, glass, and paper.
As detailed in Alva's recent technical analysis, customers can choose between concentric and eccentric rotor configurations based on their typical particle size range. Eccentric designs excel with fine particles down to 2–3 mm, while concentric designs deliver robust performance with larger piece sizes.
No modern recycling line is complete without comprehensive environmental protection. Every Alva aluminum scrap processing line is equipped with a pulse-jet baghouse dust collection system that captures airborne particulates at all transfer points and crushing chambers.
The system achieves filtration efficiency above 99.5%, ensuring exhaust emissions meet the strictest international environmental standards. Optional configurations include activated carbon adsorption units for removing volatile organic compounds released from paint and coating decomposition, enabling facilities to comply with even the most stringent regional environmental regulations.
What distinguishes Alva Machinery Group's aluminum recycling line from standard crushing equipment is its systematic approach to maximizing both recovery rate and product quality while minimizing operating costs.
High metal recovery with minimal oxidation loss. By optimizing crushing speed and cutter geometry, Alva's system generates significantly less fine aluminum dust compared to conventional hammer mills. Since fine dust particles suffer high oxidation loss during smelting – sometimes exceeding 20% – reducing fines production directly translates to higher metal yield and greater revenue for the operator. Industry data shows that optimized pre-processing can reduce smelting oxidation loss from 20% to approximately 5%, representing a massive improvement in material utilization.
Modular design for flexible configuration. The production line is built on a modular architecture, allowing customers to start with a basic configuration and add capabilities as their business grows. For facilities processing relatively clean production offcuts, a simpler two-stage crushing + magnetic separation configuration may be sufficient. For mixed post-consumer scrap, the full shredding + crushing + magnetic + eddy current + dust collection cascade delivers maximum purification.
Intelligent automation for stable operation. The entire line is controlled by a centralized PLC system with real-time monitoring of motor current, bearing temperature, vibration levels, and conveyor load. The system automatically adjusts feed rate based on crusher load, triggers alarms for abnormal conditions, and records operational data for production analysis. This reduces reliance on skilled operators and ensures consistent performance 24 hours a day.
Heavy-duty construction for long service life. All core equipment uses premium wear-resistant materials. Shredder cutters are forged from high-chromium alloy steel and are resharpenable and replaceable. Crusher hammers are made of high-manganese steel with work-hardening properties that actually increase hardness during operation. This focus on durability means lower spare parts consumption and longer intervals between maintenance overhauls.
Comprehensive capacity range. Alva offers production lines with throughput capacities from 500 kg/h for small-scale recycling operations up to 10–20 t/h for large industrial scrap processing centers. Custom engineered solutions for even higher capacities are also available for major recycling hubs and smelter feed preparation facilities.
