Eriez updates eccentric eddy current separators to increase performance, minimize maintenance
Eriez Separation and Recycling Product Manager Chris Ramsdell says the company consulted with recycling customers and designed the RevX-E to meet their needs. He explains, "We consistently heard the same demands from customers: they wanted high power with low maintenance, minimal downtime and a longer service life. We delivered on all these points with our RevX-E Eddy Current Separator."
Eriez' RevX-E Eddy Current Separators feature an eccentrically mounted magnetic rotor within a non-conductive shell for separation of nonferrous metals. The rare earth rotor produces a powerful field focused at the end of the belt.
"We thought a lot about ease of maintenance when developing this machine," says Ramsdell. The RevX-E's updated design takes up less floor space and incorporates a cantilevered frame which enables maintenance staff to change the belt in less than 10 minutes. A new hood with adjustable splitter allows operators to handle nonferrous materials in varying sizes and ensures optimum separation. Large access panels all around the machine make entry for maintenance hassle-free.
The RevX-E is available in two models: ST22 and LT2. Both models are manufactured on the same eddy current separator framework. Ramsdell says the only difference between the ST22 and LT2 is the magnet configuration on the rotor assemblies.
ST22 features a 22 pole rare earth eccentric rotor and is designed to handle fine materials that are less than 1-inch. This rotor option offers a high pole change frequency for removal of fine nonferrous metals from shredded plastics / PET flake.
LT2 features an eight pole rare earth eccentric rotor and is designed to handle 1-inch and larger coarse materials. This rotor option offers a deep, high-powered eddy current field that allows for the removal of larger nonferrous metals such as crushed aluminum cans from a PET bottle stream.
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.
