With the in-depth advancement of the global resource recycling strategy, waste aluminum recycling and reprocessing has become a core track in the field of energy conservation and environmental protection. However, heavy non-ferrous metals such as copper and lead in waste aluminum are often contaminated with oil stains. The industry pain points of low efficiency and poor precision in manual separation have seriously restricted the large-scale development of the recycling industry.
From the perspective of domestic and foreign technical research, although solutions such as heavy medium mineral processing and parabolic separation have their own characteristics, they generally face problems such as difficulty in medium screening, high equipment costs, and limited adaptability. Against this background, relying on its accumulated technical experience in the crushing and separation field, Alva Machinery Co., Ltd. has launched an integrated solution of waste aluminum metal crusher production line + eddy current separator, which solves industry problems with innovative technology and injects efficient impetus into the waste aluminum recycling industry.
I. Prominent Industry Pain Points Call for Imperative Technological Innovation
In the waste aluminum recycling process, the efficient separation of heavy non-ferrous metals and aluminum is a key link to improve resource utilization. The traditional manual separation method not only has high labor intensity and low sorting efficiency, but also is affected by oil contamination, making it difficult to achieve precise separation, which leads to resource waste and a decline in recycling benefits. Among the existing separation technologies, the heavy medium mineral processing method has a high dependence on special fluid media, resulting in high technical thresholds and operating costs; although the parabolic separation method has a simple principle, the price of mature foreign equipment is expensive, and domestic research is still in the R&D stage, which is difficult to meet the actual needs of small and medium-sized enterprises. The industry is in urgent need of an integrated solution with high efficiency, economy and stability to promote the transformation of waste aluminum separation from "extensive" to "refined".
II. Core Equipment Collaboration to Build an Efficient Separation System
Based on the actual needs of the waste aluminum recycling scenario, Alva Machinery takes "crushing pretreatment + precise separation" as the core logic to create a full-process solution. Its core advantages are reflected in the collaborative innovation and technological breakthroughs of the equipment:
(1) Waste Aluminum Metal Crusher Production Line: "Efficient Demolition Expert" in the Pretreatment Link
As a key pretreatment equipment before separation, Alva's waste aluminum metal crusher production line adopts a heavy-duty design. Aiming at the material characteristics of waste aluminum and mixed heavy non-ferrous metals, it realizes efficient crushing, impurity removal and homogenization treatment. The equipment is equipped with wear-resistant alloy hammers and precision screening devices. During the crushing process, it effectively peels off the oil stains on the surface of waste aluminum, and at the same time crushes large pieces of waste aluminum and mixed metals into uniform particles, laying a foundation for the subsequent separation link.
The production line adopts a modular design, which can flexibly adjust the configuration according to the processing volume, and is suitable for different scenarios from small and medium-sized recycling points to large-scale recycling factories. The crushing efficiency is increased by more than 30% compared with traditional equipment, which greatly reduces the time cost of material pretreatment.
(2) Eddy Current Separator: "Intelligent Separation Tool" for Precise Separation
For the crushed mixed materials, Alva's eddy current separator takes the electromagnetic induction principle as the core to realize the efficient separation of heavy non-ferrous metals and aluminum. The equipment generates an alternating magnetic field through a high-speed rotating magnetic roller. When the mixed materials pass through the separation area, non-magnetic metals such as aluminum will generate eddy currents and then be thrown out by the repulsive force of the magnetic field. In contrast, heavy non-ferrous metals such as copper and lead are not affected by the magnetic field and fall along their original trajectory, eventually achieving precise separation of the two types of substances.
Compared with traditional separation technologies, this equipment has three core advantages: first, high separation precision - it is not affected by residual oil stains, and the separation purity of copper and aluminum can reach more than 98%; second, fast processing efficiency - the separation speed is adapted to the output capacity of the crusher production line, realizing continuous operation; third, low operating cost - no special medium is required, the energy consumption is only 60% of that of traditional equipment, and the maintenance is simple, which greatly reduces the operating burden of enterprises.
III. Full-Process Advantage Empowerment to Lead Industry Upgrading
The collaborative application of Alva Machinery's waste aluminum metal crusher production line and eddy current separator has built a closed-loop processing system of "crushing - impurity removal - separation", and its comprehensive advantages run through the entire process of waste aluminum recycling:
Efficient Collaboration: The homogenization treatment of the crusher production line and the precise separation of the eddy current separator form a seamless connection, avoiding secondary pollution during material transportation. The overall processing efficiency is increased by more than 50% compared with traditional processes;
Wide Adaptability: It can handle waste aluminum materials containing various heavy non-ferrous metals such as copper, lead and zinc. Whether it is waste aluminum profiles, aluminum product scraps or mixed metal waste, efficient separation can be achieved;
Energy Conservation and Environmental Protection: The equipment adopts a low-noise design and energy-saving motors. During the crushing process, the initial peeling of oil stains is completed simultaneously, and there is no waste water or residue discharge in the separation link, which meets the green production standards;
Economical and Practical: Compared with foreign parabolic separation equipment, the investment cost is reduced by more than 40%. In addition, the later maintenance cost is low and the supply of spare parts is timely, which fully meets the cost-effectiveness needs of domestic enterprises.
IV. Deeply Engaging in Resource Recycling to Contribute to Green Development
As an innovative enterprise in the field of resource recycling, Alva Machinery has always taken "empowering environmental protection with technology and serving the industry with equipment" as its mission. The waste aluminum separation integrated solution launched this time not only solves many pain points of traditional separation technologies, but also provides a practical path for waste aluminum recycling enterprises to reduce operating costs and improve resource utilization through its advantages of high efficiency, precision and economy. At present, this solution has been applied in many recycled aluminum enterprises, helping customers increase recycling benefits by 20%-30% and winning wide market recognition.
In the future, Alva Machinery will continue to focus on technological innovation in the field of waste metal recycling and processing, continuously optimize equipment performance and solutions, and promote the upgrading of separation technology towards intelligence, scale and low-carbonization. At the same time, the company will work hand in hand with industry partners with a more complete service system and more professional technical support to contribute to the high-quality development of the resource recycling industry and the global energy conservation and environmental protection cause.
