Cheap Eddy Current Separator

A cheap eddy current separator is not a compromise, but a conscious engineering choice. We have seen more than once how expensive imported models are installed on processing lines, and after 8-12 months they are faced with three problems: high cost of service, delays in the supply of spare parts and inconsistency with real conditions - humidity, dust, overload of fractions. The eddy current separator from LONGI Corporation solves all this - without compromising the quality of separation of non-ferrous metals.

Why "cheap" does not mean "weak"

The cost of an eddy current separator does not depend on a marketing add-on, but on three things: design simplicity, localization of production and rejection of redundant functions. LONJI has its own production site in Fushun (140,000 m²), its own foundries, qualified engineers (more than 60% with higher education) and a full assembly cycle - from winding coils to testing on a vibration stand. This allows you to eliminate intermediaries, reduce logistics and avoid exchange rate risks. Result: separators of the LJ-VT series with a working width of 1000–2000 mm are 28–35% lower than analogues of European brands with an identical principle of operation and a comparable resource - up to 12 years with daily operation of 16 hours.

But the main thing is that “cheap” here refers to the total cost of ownership (TCO), not just the price on the website. For example, one of our clients in Yekaterinburg compared two options: an imported separator for 14.2 million rubles and LJ-VT-1600 for 9.7 million rubles. A year later, the calculation showed: the cost of servicing the first exceeded 2.1 million rubles (including customs, certification and repair of the coil abroad), while for LONGI it was 380 thousand rubles (local service, spare parts warehouse in Moscow, replacing the coil in 4 hours). The total savings are 4.1 million rubles.

Where it works - and where it should not be installed

An eddy current separator is effective only if three conditions are met: clear granulometry of the input material (from 3 to 80 mm), minimum moisture content (<8%), absence of ferromagnetic impurities above 0.3%. If these parameters are violated, even the most expensive separator will screen up to 18% of aluminum or copper. We always require a sample of raw materials before selecting a model. In practice, 6 out of 10 requests for “cheap eddy current separator” come from enterprises that plan to put shredder crumbs into it without preliminary screening. This is a mistake. First - a vibrating sieve, then - a separator.

The best results of LJ-VT are shown on recycled materials:

• Aluminum waste after dismantling windows and facades (yield purity - 99.2%);
• Copper wires after cleaning from insulation (Cu yield - up to 99.6% with a fraction of 5–25 mm);
• Mixtures of non-ferrous alloys from scrap electronics (Zn, Al, Cu, brass - separation into three streams).

Not suitable for: fine powder (less than 2 mm), highly oxidized aluminum (Al₂O₃ film reduces conductivity), as well as materials with a high content of steel or cast iron - these are removed in advance with a magnetic separator. We equip LJ-VT with magnetic drums of the LJ-MB series - this is a standard design on our lines.

How to choose a specific model - without overpayment

The key parameter is not power, but linear flow speed and conveyor width. For a flow of 8–12 t/h, the LJ-VT-1200 (width 1200 mm, power consumption 11 kW) is sufficient. At 18–22 t/hour you need LJ-VT-1800 (18 kW, width 1800 mm). Rotor rotation motor power is 5.5 kW for all models. Important: the rotor does not require frequency adjustment - it operates at a constant speed of 3000 rpm, which increases reliability and reduces failures.

Three proven solutions for common tasks:

• For small scrap collection points:LJ-VT-1000 with manual gap adjustment and mechanical outlet - from 7.4 million rubles;
• For medium-sized processors:LJ-VT-1400 with automatic gap control and PLC control - from 8.9 million rubles;
• For integration into automated process control systems:LJ-VT-2000 with Modbus RTU interface and winding temperature sensors - from 11.2 million rubles.

All models undergo 72-hour stress testing at the Fushun plant. Warranty - 24 months. After-sales service - within 48 hours in Russia and Kazakhstan.

What remains behind the scenes - but decides everything

“Cheap eddy current separator” is not just the price of equipment. This is the availability of technical documentation in Russian (without machine translation), the possibility of an on-site commissioning complex with a metallurgical engineer, and not just an electrician, and access to a database of 147 types of recyclable materials with recommendations for configuration. We record every case - for example, when processing scrap cast aluminum parts (A380, A390), it is necessary to reduce the conveyor speed by 12% and increase the deflection angle by 3°. Such nuances are not in the instructions - they are in experience. For 31 years, LONGI has produced more than 4,000 units of equipment. This experience is in every LJ-VT.

If you are lookingcheap eddy current separator, which does not require compensation for a low price with increased labor intensity or downtime - start with an analysis of your faction and operating mode. This is the only way to choose a model that will work accurately, without modifications and hidden costs.
