From July 8 to 10, 2026, the Shanghai International Aluminum Industry Exhibition will be held at the Shanghai New International Expo Centre. As a global provider of complete equipment solutions for scrap metal recycling, Shandong Alva Machinery Group Co., Ltd. will showcase its full range of core metal crushing and sorting equipment and customized turnkey solutions at this exhibition, comprehensively demonstrating the Group's technical accumulation and global layout achievements in the scrap metal recycling field.
Following the previous article focusing on the core star equipment - the Broken Bridge Aluminum Crusher, this article, as the second part of the series of exhibition previews, will focus on the key equipment for precise separation of non-ferrous metals in the scrap metal recycling industry chain - the Alva Eddy Current Separator. It will comprehensively interpret its technological innovations and design concepts targeting the pain points of the global non-ferrous metal sorting industry, as well as the application value and market prospects of this equipment in the global recycled aluminum, recycled copper and other non-ferrous metal recycling fields.
Driven by the global circular economy and the "dual carbon" goals, the recycled non-ferrous metal industry has become the core pillar of the sustainable development of the global non-ferrous metal industry. Among them, recycled aluminum, with its significant energy-saving and carbon-reduction advantages, has become the fastest-growing and largest sub-sector in the recycled non-ferrous metal industry. With the rapid development of the global recycled aluminum industry, downstream smelting and processing enterprises have continuously raised the requirements for the purity of recycled aluminum raw materials. The content of non-ferrous metal impurities in raw materials directly affects the quality, performance and market value of recycled aluminum products.
In the scrap metal recycling process, after the crushing process, the materials contain not only the target aluminum materials but also non-ferrous metals such as copper, zinc and stainless steel, as well as non-metallic impurities such as plastics, rubber and glass. Traditional sorting methods mainly rely on manual sorting and ordinary magnetic separation, which have many insurmountable limitations: manual sorting has high labor intensity, low operation efficiency and unstable sorting accuracy, and cannot achieve large-scale continuous production; ordinary magnetic separation can only separate ferromagnetic metals and is completely ineffective for non-ferromagnetic non-ferrous metals such as copper and aluminum. These traditional sorting methods lead to excessive content of non-ferrous metal impurities in recycled aluminum raw materials, which not only increases energy consumption and production costs in the subsequent smelting process, but also seriously affects the mechanical properties and chemical composition stability of recycled aluminum products, limiting the application of recycled aluminum in high-end fields.
With the continuous rise of global labor costs and the increasingly strict environmental regulations, traditional sorting methods can no longer meet the development needs of the modern recycled non-ferrous metal industry. The market urgently needs a dedicated equipment that can achieve efficient, precise and automated separation between non-ferrous metals and non-metals, and between different types of non-ferrous metals. Eddy current separation technology, as one of the most advanced non-ferrous metal sorting technologies in the world, has become an indispensable core equipment in the global scrap metal recycling production line due to its advantages of high sorting efficiency, high degree of automation and low operating cost.
Based on years of technical accumulation in the field of metal sorting, Alva Machinery Group has conducted in-depth research on the composition characteristics and processing process requirements of scrap metal materials in different regions around the world. Aiming at the problems of low sorting accuracy, poor adaptability and unstable operation existing in traditional eddy current separators, it has developed a new generation of Alva Eddy Current Separator for the global market, providing an efficient and reliable non-ferrous metal sorting solution for the global recycled non-ferrous metal industry.
The Alva Eddy Current Separator is a dedicated equipment designed for the separation of non-ferrous metals and non-metals in the scrap metal recycling process, which realizes material separation by using the principle that conductors generate induced eddy currents in a high-frequency alternating magnetic field. The equipment has been comprehensively optimized from multiple dimensions including the sorting core, feeding system, intelligent control and structural design, which can effectively separate non-ferrous metals such as copper, aluminum and zinc from various scrap metal materials, and has the characteristics of high sorting accuracy, strong adaptability, stable operation and easy maintenance. The equipment design fully considers the power standards, material characteristics, operating environments and safety regulations in different regions around the world, and can meet the diverse needs of the global market.
The equipment adopts the modular integrated structure design concept, which independently designs and integrates functional modules such as the feeding unit, sorting main engine, discharging unit and electrical control unit. Each module is connected through standard interfaces, facilitating the overall transportation, on-site installation and later maintenance of the equipment. The modular design also enables the equipment to be flexibly configured and laid out according to the actual processing needs and site conditions of customers, adapting to the use requirements of production enterprises of different scales.
The equipment frame is welded with high-strength section steel, and undergoes overall stress relief treatment after welding, which can effectively absorb the vibration generated during the operation of the equipment, avoid frame deformation and structural loosening caused by long-term operation, and ensure the structural stability and service life of the equipment. The surface of the frame is treated with multi-layer anti-corrosion and anti-rust treatment, which can adapt to the complex operating environments of scrap metal recycling workshops in different regions, such as humidity, dust and strong corrosion. The overall layout of the equipment has been optimized, and sufficient operation and maintenance space is reserved, facilitating operators to carry out daily inspections, replacement of wearing parts and equipment maintenance.
The sorting core system is the core component of the eddy current separator, and its performance directly determines the sorting accuracy and separation effect of the equipment. The sorting core system of the Alva Eddy Current Separator is mainly composed of a high-frequency alternating magnetic roller, a sorting belt, a driving device and an adjustment mechanism, which has been comprehensively optimized for the characteristics of scrap metal materials in different regions around the world.
The high-frequency alternating magnetic roller is made of high-permeability rare earth permanent magnet materials, and the magnetic pole arrangement and magnetic field distribution structure are optimized, which can generate a high-intensity and high-frequency alternating magnetic field. When non-ferrous metal materials pass through the alternating magnetic field area, strong induced eddy currents will be generated inside them. The magnetic field generated by the eddy currents interacts with the original magnetic field, giving the non-ferrous metal materials a forward repulsive force, thereby realizing separation from non-metallic materials. The rotation speed and magnetic field strength of the magnetic roller can be steplessly adjusted according to the material characteristics, which can adapt to the sorting needs of non-ferrous metal materials with different particle sizes and different materials.
The sorting belt is made of high-strength, wear-resistant and anti-static special rubber materials, which has good tensile strength and wear resistance and can meet the requirements of long-term continuous operation. The running speed of the belt can be accurately adjusted through the frequency conversion system, and operators can adjust the belt speed according to the particle size and density of the materials to achieve the best sorting effect. The sorting belt adopts a quick-replaceable structure design. When the belt is worn to the replacement standard, operators can complete the replacement of the belt in a short time, reducing equipment downtime and maintenance time.
The sorting chamber adopts an optimized flow channel design, which can guide materials to enter the sorting area evenly and smoothly, avoid material accumulation and splashing, and improve sorting accuracy. At the same time, the sorting chamber is equipped with an adjustable material distribution baffle. Operators can adjust the baffle position according to the separation effect of materials to realize precise diversion of non-ferrous metal and non-metallic materials.
Uniform and stable feeding is the key to ensuring the sorting effect of the eddy current separator. The Alva Eddy Current Separator is equipped with a dedicated vibrating feeding device, which can realize continuous, uniform and quantitative conveying of materials, avoiding fluctuations in sorting effect caused by uneven material feeding. The vibration frequency and amplitude of the feeding device can be adjusted according to the material characteristics, which can effectively break up agglomerated materials, ensure that materials enter the sorting area in a single layer, and improve sorting accuracy.
Aiming at the problem that some materials contain large particle impurities and long strip materials, the equipment can be equipped with a pre-screening and impurity removal device to remove large particle impurities and long strip materials in advance, preventing them from entering the sorting chamber and damaging the sorting belt and magnetic roller, and at the same time avoiding large particle materials affecting the sorting effect of small particle materials. The pre-pretreatment system and the sorting main engine realize linkage control, which can automatically adjust the feeding amount according to the operating state of the sorting main engine to ensure the continuous and stable operation of the equipment.
The equipment adopts a PLC programmable logic controller as the control core, equipped with an industrial color human-machine interface (HMI) touch screen, realizing fully automatic operation and intelligent management of the equipment. Operators can intuitively set the operating parameters of the equipment through the touch screen, including magnetic roller speed, belt speed, feeding amount, material distribution baffle position, etc., to meet the sorting requirements of different materials. The control system supports multi-language switching, which can meet the use needs of customers in different countries and regions around the world.
The control system has a real-time status monitoring function, which can display the operating parameters of the equipment such as current, voltage, temperature and speed in real time, as well as the working status of each component. When the equipment is abnormal, the control system will automatically trigger the sound and light alarm device and display the fault code and fault location on the touch screen, facilitating operators to quickly troubleshoot and deal with faults. At the same time, the control system has fault self-diagnosis and protection functions. When serious faults such as overload, overheating and belt deviation occur, the equipment will automatically shut down to avoid equipment damage caused by fault expansion.
The control system also reserves standard communication interfaces, which can realize linkage control with other equipment of the entire line, ensure the coordinated operation of the entire scrap metal crushing and sorting production line, and realize full-process automation from feeding, crushing, sorting to discharging. At the same time, it supports remote monitoring and data transmission functions, facilitating the Group's technical team to provide remote technical support, fault diagnosis and equipment upgrade services for global customers.
In the process of equipment design, energy consumption control and environmental protection requirements in different regions around the world are fully considered. By optimizing the structure of the transmission system and adopting high-efficiency energy-saving motors and high-precision reducers, the loss during energy transmission is reduced and the energy utilization efficiency of the equipment is improved. The magnetic roller of the equipment is driven by permanent magnet materials, which does not require an additional excitation power supply, further reducing the operating energy consumption of the equipment.
The equipment is equipped with a dedicated sealed dust removal device, which can effectively collect the dust generated during the sorting process and discharge it up to standard after filtration treatment, improving the workshop operating environment and meeting the environmental protection emission standards of major countries and regions in the world. At the same time, the noise generated during the operation of the equipment has been effectively controlled. By adopting measures such as shock absorption bases and sound insulation covers, the equipment operation noise is controlled within the allowable range of industrial places, protecting the occupational health of operators.
The equipment is equipped with a comprehensive safety protection system, which fully complies with the industrial safety standards of major countries and regions in the world, and guarantees the personal safety of operators and the operation safety of the equipment. Safety guardrails and safety interlock devices are installed in dangerous areas such as the feeding port, discharging port and sorting chamber inspection port. When the safety protection device is opened or triggered, the equipment will stop running immediately to prevent operators from entering the dangerous area by mistake.
Emergency stop buttons are installed at multiple key positions of the equipment. Operators can press the emergency stop button at any time to stop the equipment immediately when abnormal conditions are found. The electrical system adopts multiple safety measures such as insulation protection, grounding protection, leakage protection and overload protection to avoid electric shock accidents and equipment damage. All safety protection devices have undergone strict testing and verification to ensure their reliability and effectiveness.
