Cheap High Intensity Wet Electric Magnetic Separator

Cheap high intensity wet electric magnetic separator is not a marketing phrase. This is a real solution that we have implemented in 17 concentrators over the past three years. In each case, the client set one goal: to remove weakly magnetic impurities from the sludge at minimal capital and operating costs. And every time, the separators of the LJM-WHIS series accomplished it - without overloading the generators, without constantly stopping for cleaning, without replacing the coils every 8 months.

Why "cheap" does not mean "unreliable"

We often hear from customers: “If the price is lower than the market average, where’s the catch?” There is no catch. We just eliminated everything unnecessary. We do not skimp on copper in the winding - we use only OFHC copper (99.99% purity). We do not reduce the thickness of the steel frame - it is designed for a pressure of 2.8 MPa during hydrotesting. Savings occur where they do not affect the service life: in logistics (production and assembly - on one site in Fushun), in standardization (6 basic models cover 92% of tasks for quartz, iron ore, titanium concentrates), in the refusal of “smart” interfaces that require service.

Average installation cost Cheap high-intensity wet electric magnetic separator LJM-WHIS-1200 - from 4.2 million rubles. For comparison: similar solutions from Western manufacturers start at 7.8 million. The difference is not in the configuration, but in the fact that we do not integrate controllers into the system with a subscription to cloud updates and do not require certified engineers for annual calibration.

What breaks other separators - and why ours works

In 2023, we analyzed 43 cases of failure of wet SIMS from competitors. In 68% of cases, the cause is overheating of the coil due to frequent on/off cycles. We don’t have this: the LJM-WHIS cooling system operates on the principle of forced circulation of distilled water with thermal stabilization of ±0.5°C. The winding temperature does not exceed 65°C even at 100% load 16 hours a day.

The second common problem is clogging of the magnetic channel. Our separators are equipped with two independent flushing circuits: the main one (at a pressure of 0.4 MPa) and the emergency one (triggered when the flow rate drops by 15%). The channels are made of stainless steel 1.4404 with a polishing Ra ≤ 0.4 µm - no sediment is retained.

• Operating magnetic field: up to 2.4 Tesla in the separation zone
• Field gradient: 320 T/m (fixed, not adjustable)
• Capacity: 8–120 m³/h (depending on model)
• Fe₂O₃ purification rate from quartz sand: 99.3% with particle size 15–45 µm

How to choose - and what not to expect

A low-cost, high-intensity wet electric magnetic separator solves a clear problem: removing ferromagnetic and weakly magnetic inclusions from suspensions with a solid phase content of up to 45%. It does not replace gravity or electrostatic separators. It does not work with dry materials. It is not suitable for ores with high clay content without prior classification.

Before choosing, check three parameters:

1. Concentration of the solid phase in the pulp— if above 48%, preliminary decanting is necessary;
2. Particle size of target mineral- when a faction dominates<10 µm efficiency drops by 12–18%;
3. Presence of aggressive components— at pH<2.5 or >10.5 requires modification of the body made of KhN78MBT alloy.

What's next - and why has it already started?

In 2024, we are launching a program to modernize existing separators: replacing outdated power supplies with new LJM-PowerX IGBT modules with an efficiency of 94.7% and built-in protection against voltage surges. This reduces energy consumption by 22% and extends the life of the coil by another 3 years.

A cheap high intensity wet electric magnetic separator is not a temporary measure. This is the technological entry point into the sustainable recycling system. He works where others refuse: in conditions of unstable voltage, in highly dusty workshops, in the absence of a full-time electrician. Its strength is predictability. What you know for sure is that in 3 years it will work the same as on day one. No surprises. No extra charges. No compromises.
