Scrap metal shredders are a key link in optimizing scrap metal recycling

As an important piece of equipment for scrap metal recycling, the scrap metal shredder plays a key role in the scrap metal processing industry. Its working principle and impurity removal and sorting process play a vital role in achieving efficient scrap iron processing and resource recycling.

1. First, during the feeding stage of the scrap iron shredder, the scrap iron is transported to the feed port of the shredder, usually through a conveyor belt or other conveying equipment. This stage may require preliminary pre-treatment of the scrap iron to ensure that it adapts to the working requirements of the shredder. This includes cleaning up large pieces of scrap iron to reduce the burden on the shredder in subsequent work.

2. The next step is the shredding stage. After the scrap iron enters the shredder, the material is powerfully sheared and shredded by the internal blade shredding component, and the scrap iron material is shredded into smaller pieces. The goal of this stage is to effectively shred large pieces of scrap iron into smaller particles to facilitate subsequent sorting and processing.

3. The sorting and impurity removal stage is a key link in the entire process. Scrap iron fragments will contain certain impurities after being shredded, such as coating, oil, plastic, etc. In order to improve the quality and recycling rate of scrap iron, impurity removal and sorting are required. This process can use a variety of physical methods, among which vibrating screening and magnetic sorting are common technologies.

a. In vibrating screening, through vibrating screening equipment, scrap iron fragments will be transferred to screens with different sized mesh holes to achieve particle classification. This helps remove some of the smaller or larger impurities and improves the purity of the scrap iron.

b. Magnetic sorting uses the ferromagnetic properties of scrap iron to separate ferromagnetic scrap iron from non-ferromagnetic impurities through magnetic separators and other equipment. This step effectively removes some impurities other than metal, further improving the quality of scrap iron.

The ultimate goal of the entire work process is to make scrap iron fragments reach a quality that meets recycling standards and provide high-quality raw materials for scrap metal recycling. This has a positive effect on environmental protection and resource recycling. To sum up, the scrap iron shredder enables efficient processing of scrap iron through shredding, impurity removal and sorting, making it a valuable resource for recycling. This process is not only beneficial to environmental protection and reduces the negative impact of scrap metal on the environment, but also provides support for the sustainable development of the scrap metal recycling industry.
