Goudsmit redesigns its eddy current product line

Waalre, Netherlands-based Goudsmit Magnetic Systems BV says it has redesigned its line of eccentric eddy current separators to include technical improvements while also reducing the cost.

The goal of the redesign effort was improved ease of use, durability and ROI (return on investment), says the company. In a news release announcing the redesign, Goudsmit says “Special focus was placed on the frame, accessibility for service and the magnetic rotors. The quality function deployment (QFD) method was used to analyse customer needs and market trends.”

Based on the QFD results the separator line was “completely redeveloped and optimized, but with the

understanding that no compromises would be made as concerns separation requirements, finish

level and quality,” says Goudsmit. The company says buyers use its eddy current separators to remove nonferrous metals from material streams such as incinerator slags, shredder residues, glass, wood, construction and demolition waste, electronic scrap and municipal solid waste (MSW).

Postredesign, the eccentric magnetic rotor can be adjusted to different angles relative to the outer shell, allowing for adjustments to the ejection moment of the nonferrous metals. Because the magnetic rotor is mounted off-centre in the outer shell, iron particles cannot adhere to the outer shell; this prevents burn-in problems, says Goudsmit.

Models within the Goudsmit eddy current line include:

• the EddyCan, which contains a 10-pole magnetic rotor and is suitable for separation of aluminium cans and coarse particles from lightweight bulk material and recycling streams;
• the EddyXpert, which is fitted with a 12-pole magnetic rotor and is suitable for coarse fractions containing particles 80 millimetres (three inches) and larger; other versions have 18-pole and 22-pole magnetic rotors for smaller fractions; and
• the EddyFines, which contains a 38-pole magnetic rotor and is suitable for the finest fractions (smaller than 5 millimetres, or one-fifth of 1 inch).
