Recovery of automobile shredder residues (ASR-SLF-SHF)
Improving the recycling rate of end-of-life vehicles is a hot concern for the automotive industry worldwide. In end-of-life car sorting, a commonly designed shredder system is used first. Then, air separation is applied to get the light fraction, known as the shredder light fraction (SLF). After that, the heavy items are called shredder heavy fraction (SHF). In the end-of-life car dismantling and recycling process, about 75 percent of automobile materials can be recycled, and the remaining 25 percent is fluff.
First, manual dismantling is done for reusable parts. Then, other parts are shredded and different metals are separated. Metals in end-of-life vehicles (ELVs) include iron, ZORBA, stainless steel, aluminum, copper, magnesium alloys, small amounts of zinc, lead, bearing alloys, cast iron materials, etc., about 40 different materials.
Ferrous metals in automobiles account for about 80%. Non-ferrous metals account for about 3%-4.7% of the crushed metal materials. Other crushed materials of automobiles are automobile shredder residue (ASR). ASR consists of a wide variety of materials, including plastics, glass, rubber, wood, foam, tramp metal, wire, fibers, sand, and dirt.
Customized modular design ready to clean your SLF/SHF material, sieve & separate material
Our ASR and Scrap Metal processing uses a customized modular design. Our robust machines can handle any input ASR material—the residual shredder light and heavy fractions. For any throughput, any output size after shredding, either setting up a new system or system upgrades are available.
Generally, the shredder heavy fractions (SHF) use high-efficiency sieving, manual picking, and automatic picking for integrated fine sorting to obtain valuable components. Magnetic separators (including suspension magnets, magnetic head pulleys, magnetic drums, etc.) are used to remove coarse ferrous and fine ferrous metal. Eddy current sorting (including eccentric eddy current separators, concentric eddy current separators, etc.) is chosen to recover non-ferrous metals in ASR, such as Zorba, fine Zorba, and aluminum. Sensor sorters with different functions are used to continue removing stainless steel and copper wire.
ASR shredded material uses the trommel screen (sieving method) to separate materials. The trommel is also known as a rotary screen. Raw material after shredding comes in different sizes, which are separated by physical size. Undersize material is output through the screen and enters the sorting system. Oversize material exits at the other end of the drum.
We struggle for entire separation and sorting for every metal in ASR
Ferrous metal recovery technology for automotive shredder residue (ASR)
Among the metal materials obtained from the dismantling of automobile crusher residue (ASR), steel materials can be separated from other materials by a magnetic separator. This is a relatively simple process. The proportion of non-ferrous metals in automotive shredder residue (ASR) has high use value.
Our suspension magnet is used to recover magnetic particles from industrial waste, etc., and is utilized to protect crushers and belt conveyors that subsequently treat the material. Similarly, the drum magnet has high magnetic strength and is typically placed at the end of the conveyor belt. It saves money, time, and labor by reducing downtime and improving quality, providing maximum protection for mills, crushers, shredders, and related equipment. Our drum magnets are classified as permanent magnetic drums and electromagnetic drums; both types are effective in separating weakly magnetic materials from non-magnetic materials. In the steel scrap recycling industry, Our electro drum magnetics are commonly used, which contain larger bearings and bearing housings with replaceable wear covers to help extend the life of the drum shell.
Non-ferrous metal recovery technology for automotive shredder residue (ASR)
The quality of our eddy current separators has been recognized by customers worldwide. The sorting efficiency of the eccentric eddy current separator is more than 99%. The eccentric eddy current separator is currently widely used in ZORBA recycling and is a reliable solution for the reuse of non-ferrous metals, particularly from scrap car crushing materials. Through long-term accumulated experience in designing, manufacturing, and producing for different automotive shredder residue factories.
We learnt through each influencing factor on ASR sorting efficiency. In the field of scrap car recycling, fine fractions are difficult to recycle. We are dedicated to optimizing the process of eddy current separators in industrial applications. We research the new structure of fine particle sorting - our concentric eddy current separator and ECS automatic control system, aiming to recycle micro-fine aluminum with a 1-2mm grain size.
Our ASR premium sorting solutions offer superior removal
The cleaner your fraction cleaning, the higher the yield, and the more money you make.
We offer a highly sensitive sensor sorter to efficiently separate materials for Automotive Shredder Residue (ASR). The non-metallic materials obtained after car dismantling and crushing are glass, fiber, rubber, automotive fluid, plastic, and dirt, with glass, plastic, and rubber being the main ones. Among them, glass can be separated by wind sorting due to its high density. The sorting technology for crushed plastic materials uses their specific gravity and different shape coefficients: crushed plastic materials are put into the gravity screening chamber from the top, and airflow of certain strength is added at the lateral position to separate plastic and metal materials.
Induction sorting systems and image sorting systems combine with intelligent sensor sorters for stainless steel, shredder fibers, Zurik, wire chopping, copper wire, and shredder granules.
Recently, our three eccentric eddy current separators, suspension magnets, drum magnets, trommel screens, and induction sorters were sent to an ASR recycling company in Australia to separate non-ferrous metals mixed in ASR, such as aluminum and copper. The estimated processing capacity can reach 300 tons per day.
