What Are The Processes For Recycling Scrap Aluminum?
Aluminum is one of the most recycled and in-demand metals in the world. Recycling scrap aluminum uses only 5% of the energy used to develop new aluminum, and the pollutants emitted during the production of recycled aluminum are only 10% of the pollutants generated during the production of original aluminum. Therefore, recycling scrap aluminum is a green, environmentally friendly and profitable business. In addition, aluminum is infinitely recyclable, which means it can be recycled over and over again without changing its physical properties.
Aluminum and aluminum alloy products are widely used in our daily life, such as cans, doors and windows, electronic products, building templates, cars, etc. In recent years, the demand for aluminum has gradually increased, and the price of aluminum has also experienced multiple rounds of increases. Increasing the amount of aluminum recycling has become an urgent task. So, what are the processes for recycling scrap aluminum?
1. Collection
Collect various aluminum products (including beverage cans, aluminum foil, aluminum parts and other waste aluminum products) from manufacturing plants, homes, car recycling plants, recycling stations, or construction sites.
2. Crushing
Using a shearing shredder to break the waste aluminum into small pieces makes it easier to remove the packaging coating and paint on the material, and facilitates subsequent sorting and extraction.
3. Sorting
Most of the collected waste aluminum contains mixed materials. For example, steel cans, scrap iron, etc. Therefore, it is necessary to separate these materials from the aluminum to improve the purity of the waste aluminum recycling. According to different material requirements, use appropriate sorting equipment such as magnetic separation, eddy current separation, specific gravity separation, etc. to separate the mixed aluminum, metals and other substances.
4. Cleaning
Use physical or chemical processes to clean the shredded waste aluminum.
5. Melting
The waste aluminum is sent to a high-temperature furnace and melted at a temperature of more than 1700 degrees Celsius. In addition, adding metals such as copper, zinc, magnesium or silicon in a molten state can make aluminum alloys.
6. Cooling and forming
The molten aluminum is poured out and formed into ingots, which are then transported to aluminum processing or manufacturing plants to be made into new products.
The scrap aluminum shredder is the most important and indispensable equipment in the recycling process, so it is crucial to choose a suitable and high quality scrap aluminum shredder. As an expert in the recycling of solid waste, especially metals, Gomine scrap metal shredder adopts a powerful drive system that can generate greater torque and power to ensure fast and effective crushing of various scrap metals. Compared with traditional crushing method, the scrap metal shredder can greatly improve production efficiency, reduce processing time, and thus reduce the operation costs. This scrap shredder is not only suitable for common metals such as scrap aluminum and steel, but can also be used for the crushing of non-ferrous metals such as copper, zinc, and nickel.
The working principle of the scrap metal shredder is to use the shearing force of the rotating moving blade and the fixed blade to tear the scrap metals into small pieces. Specifically, the scrap metal shredder is equipped with multiple sets of blades, and a certain distance is formed between the blades. When the scrap metals enter the machine, they are sheared and torn by the rotating blades and gradually torn into small pieces. The shredded metal pieces are screened and classified, and can be subsequently smelted and reused.
