Professional FAQ: Eddy Current Separator
Q1: What is the core material used for the rotor shell in high-quality eddy current separators?
A1: The rotor shell is typically crafted from high-strength, low-resistivity aluminum alloy (e.g., 7075-T6) to maximize induced current density and withstand centrifugal stress.
Q2: How is the separation efficiency defined and tested?
A2: Efficiency is measured as (% recovery by mass) of target metal within specified granularity, per ISO 12048; independent testing may also apply EN 14420 protocols.
Q3: What installation standards must be followed?
A3: Main requirements include conformity with machinery directives (EN 60204 for electrical safety, IEC 60034 for drive/motor standards), clearances, and ATEX compliance for dust/explosion-risk areas.
Q4: Which magnets are preferred for modern non-ferrous metal separators?
A4: Premium Neodymium Iron Boron (NdFeB, N40 grade or above) for strongest field intensity, sometimes supplemented by Samarium Cobalt for high-temperature endurance.
Q5: What is the expected operational life and maintenance interval for an ECS?
A5: Typical design life for main rotating assembly is >30,000 hours. Key maintenance tasks (bearing lubrication, belt replacement, rotor cleaning) are scheduled at 6–12 month intervals.
Q6: Can eddy current separator units be customized for mobile setups?
A6: Yes, mobile eddy current separator systems are engineered with shock-absorbing frames, quick-connect power modules, and are compliant with road transport & safety (EU ECE R48, SAE J560).
Q7: Are there recommended certifications for supplier selection?
A7: Reputable ECS manufacturers should be ISO 9001, ISO 14001 certified, and ideally provide test reports from an accredited third-party (e.g., SGS, TUV, CNAS labs).
