Vertical hammer mill crushes blocky, attached aluminum-iron mixed materials (e.g., aluminum-cased iron-core motors, aluminum-iron composite parts) into small pieces or granules, separating aluminum and iron components that were originally tightly bonded. This solves the problem of "unable to recycle aluminum and iron separately due to adhesion" and lays the foundation for subsequent sorting.During crushing, the impact and extrusion of the vertical crusher can peel off impurities such as oil stains, coatings, and oxide layers on the material surface (e.g., anti-rust paint on aluminum parts, oil stains on iron parts). This reduces the interference of impurities on aluminum and iron recycling smelting and lowers subsequent processing costs.

🚀 Upgrade aluminum can recycling efficiency, intelligent shredder helps double profits! ​​

The aluminum can recycling industry is now at a critical juncture of green transformation. However, the traditional briquetting method is inefficient and energy-consuming, which limits the profit margin! Gangzheng Machinery has specially launched high-efficiency shredders for aluminum can recycling enterprises. Through technological innovation, it addresses the pain points of the industry, helps enterprises reduce costs and increase efficiency, and seize market opportunities!

🔍 current situation and challenges of the industry
At present, although the recycling rate of aluminum cans is high (over 98% in China), most recycling enterprises still rely on briquetting machines for processing, which leads to the following problems:

Downgraded use: The aluminum material after being pressed into blocks is difficult to be precisely sorted and is often downgraded for use in low-end products, with a value loss of up to 30%!

Excessive energy consumption: The briquettes need to be crushed twice before smelting, increasing both time and energy costs.

Residual impurities: During the compression process of the briquettes, impurities such as plastic and iron rings are prone to be mixed, which affects the purity of recycled aluminum.

The "same-level recycling" (Can-to-Can) of aluminum cans is the future trend. For instance, Anheuser-Busch InBev Asia Pacific has achieved high-value utilization of 6,000 tons of waste aluminum cans through closed-loop recycling!
Is your production line ready for an upgrade?

The core advantages of 💡 steel shredder
For the characteristics of aluminum cans, Gangzheng shredder provides a one-stop solution:

High-efficiency crushing: The dual-axis shearing design directly crushers aluminum cans into uniform fragments (5-20mm) without the need for secondary treatment, increasing production capacity by 50%!

Precise sorting: Fragments can be more easily separated from impurities such as iron and plastic through magnetic separation and air separation. The purity of recycled aluminum can reach over 95%, meeting the high-level requirements of "bottle-to-bottle".

Energy conservation and consumption reduction: The melting speed of fragments is 40% faster than that of briquettes, reducing fuel costs by 30%, which is in line with the policy orientation of carbon neutrality.

Durable and intelligent: High-alloy cutting tools are wear-resistant, and the PLC system provides real-time monitoring, making it suitable for the high-temperature and high-humidity environment in Vietnam.

📊 Case sharing: Efficiency improvement for Vietnamese customers
A certain recycling plant in Vietnam originally used a briquetting machine with a daily processing capacity of only 10 tons, and the price of aluminum materials was relatively low. After switching to the Gangzheng shredder:

Processing capacity → increased to 15 tons per day;

Smelting cost → Decreased by 35%;

Aluminum material selling price → Due to the improvement in purity, there is a premium of 200 US dollars per ton!

Customer feedback: "Direct melting of fragments saves time and effort, and the investment can be recovered in half a year!"

🌟 time-limited offers and calls to action
To promote green technology, Gangzheng Machinery has launched exclusive policies for the Vietnamese market:

The first 10 customers to place an order will enjoy free equipment installation and a one-year warranty!

In the current waste materials recycling industry, competition is becoming increasingly fierce. Many bosses of recycling enterprises are pondering the same question: costs are rising, labor is decreasing, but profits are getting thinner and thinner.
Although the recycling volume of scrap metals, plastics, rubber and wood is large, manual sorting is slow, transportation takes up a lot of space, and the efficiency of compression and crushing is low, resulting in mountains of goods piling up in warehouses and slow turnover. The aging of equipment and frequent maintenance have left many business owners struggling to cope. More importantly, environmental protection requirements are becoming increasingly strict. Traditional low-efficiency equipment is no longer able to meet the emission and energy consumption standards. A slight mistake could lead to the risk of production suspension and rectification.

Gangzheng Machinery Co., Ltd. was precisely established to address these industry pain points. We have been deeply engaged in the manufacturing of shredders for over a decade. Starting from the source factory, we provide truly "efficient, durable and worry-free" equipment solutions for recycling enterprises.
Our shredders can not only easily handle various types of waste materials such as metals, plastics, tires, and wood, but also feature high torque, low energy consumption, and an intelligent control system, enabling enterprises to achieve automated crushing and sorting and significantly reduce labor costs.
More importantly, our equipment has fully taken into account environmental protection and safety requirements in its structural design. It has passed the national energy efficiency standard certification, helping enterprises smoothly pass environmental protection reviews and improve operational efficiency and brand image.

At Gangzheng, we are well aware of the difficulties faced by every recycling boss - you are not selling waste, but striving for resource regeneration and a green future.
We hope to free you from the heavy burden of daily maintenance with more reliable equipment, allowing you to focus your time and energy on truly valuable areas - making recycling more efficient, profits more controllable, and environmental protection easier.
