How to improve the separation purity of eddy current separator?

Eddy current separators play a crucial role in non-ferrous metal recovery at sites handling dismantled home appliances, scrapped vehicles, aluminum recycling, and solid waste processing.

A single eddy current separator often struggles to handle the complexities of sorting mixed solid waste materials. Drawing on years of experience in solid waste sorting solutions, SUNYGROUP maximizes non-ferrous metal recovery rates. SUNYGROUP enhances separation purity primarily through the following steps:

1. Pre-separation of ferrous metals using strong magnets: Ferrous metal components are completely removed beforehand. This prevents iron pieces from adhering to the separator belt—which could cause overheating and belt damage—and ensures a stable, efficient magnetic field output.

2. Screening and classification: Materials are sorted by particle size using trommel screens or vibrating screens. Greater uniformity in particle size allows for more precise positioning of the splitter plate, potentially increasing the recovery rate of fine metals by over 15%.

3. Uniform single-layer spreading via vibrating feeder: A high-frequency vibrating feeding system ensures materials are spread evenly and fed smoothly onto the high-speed eddy current belt in a “single-layer” formation.

4. High-frequency eccentric eddy current separator: Utilizing high-performance permanent magnets and an eccentric high-frequency magnetic system, the equipment dynamically adjusts magnetic pole angles and splitter plate positions based on material characteristics, enabling the efficient, single-pass separation of non-ferrous metals such as copper, aluminum, zinc, and magnesium.
