Bunting’s HISC high intensity separation conveyor optimizes copper recovery
According to Bunting Magnetics, the HISC High Intensity Separation Conveyor has been designed to deliver high purity recycled copper and achieve maximum separation of stainless steel and ferrous dirt in ICW wire-cleaning applications. With a first-of-its-kind design, the HISC was developed using Bunting's Magnetic Finite Element Design software technology.
According to Bunting, in the United States, nearly 45% of all copper is obtained from recycled material rather than newly mined ore. Copper's high recyclability is one of the properties that makes it such a valuable material.
In addition to being easy to recycle and repurpose, copper is also desirable due to its high malleability, its excellent resistance to rust and corrosion, its ability to effectively conduct heat and electricity, and even its antimicrobial properties. When processing copper in your recycling facility, it is important that recovered copper is pure and free of contamination from other metals.
Bunting says that when designing the HISC, their engineers were concerned with how to attract, hold and extract paramagnetic work-hardened 300 stainless steel metal. This type of paramagnetic metal, along with extremely fine particles of ferrous dirt, are both highly common as well as highly difficult to remove from ICW applications. Bunting's HISC achieves removal of these types of contaminant particle by incorporating extremely high gauss fields, neodymium rare earth magnets, and an extensively field-tested design.
The HISC is suitable for both wire pre-chopping purification as well as wire post-chopping purification in ICW wire separation applications. When used in pre-chopping applications, the HISC removes stainless steel and ferrous dirt contamination in order to prevent chopper knives from coming into contact with contaminant particles. By removing contamination, chopper knives experience significantly reduced wear and tear, resulting in a higher throughput, less knife maintenance and downtime, and overall higher profitability. In post-chopping applications, the high intensity magnetic field separation of the HISC removes stainless steel and fine ferrous contamination and greatly increases the purity and profitability of your recycled copper product.
Copper is a critical material for infrastructure, electronics, and many other industries. Because half of the United States copper supply is sourced from recycled material, it is essential that recycling companies are able to recover as much high-purity copper scrap as possible.
Bunting's new HISC excels at assisting in the recovery of pure copper, and is suitable for many other applications requiring high intensity magnetic separation, including medical stainless steel separation, electronics green board recycling, ground plastic purification, auto shredder recycling, and more.
Traditionally, waste management companies have operated using a simple "management of waste" approach to operating a MRF. Throughput targets and continuous operation (minimal downtime) were the main driving forces. The industry has changed however, and the focus moving forward is now on optimizing system performance and reliability, in conjunction with increasing recycling rates and a drive for a "greener" and more sustainable tomorrow.
When considering the addition of, or upgrade to, an "intelligent" MRF, for municipalities or private operators, the main factors should always be the client's (operator) current requirements, and evolving market needs, which include throughput, reliability, output quality, and adaptability. Equally important is a full understanding of what is really expected from any proposed system. Having an engaged and focused mindset for the project with the client from the beginning, will impact and drive the entire design process. This then impacts the overall project result, through to the productive, efficient, ongoing operation of the facility itself.
