Product features:
Electromagnetic dry powder machine is a kind of equipment mainly developed for dry powder. Its magnetic system has large Angle and multiple magnetic poles and average flux density in the magnetic system and design different field strength; the electromagnetic dry powder machine need not overcome the effect of gravity and the resistance of raw materials.When the non-magnetic mineral is separated from the magnetic field, the mineral is well separated from the magnetic medium under gravity.In addition, an adjustable mechanical vibration device is added to the electromagnetic dry powder machine, which can not only improve the effect of iron removal, but also easily achieve the iron abandonment.
Operation process:
Feed the powder from the upper feed hopper, while keep the dry powder machine in the charge magnetic state, and start a vibrator.When the feed is given, stop the feed, disconnect the excitation magnetic device, start the other vibrator (keep two vibrators simultaneously), and dial the baffle in the hopper to the iron outlet, so that the magnetic material adsorbed in the magnetic medium can vibrate down and discharge with the help of vibration force.
scope of application:
Electromagnetic dry powder machine is particularly suitable for selecting fine grain mineral particles, such as magnetic fine particle ferrous metal hematite, pseudo hematite, limonite, chromite, manganese, fine grain non-ferrous metal monazite, and fine particles of nonmetal feldspar, quartz, kaolin and other minerals.Electromagnetic dry powder machine is especially suitable for mines in arid and water shortage areas.

### **Core Technological Advantages**
**1. Industry-Leading 20,000+ Gauss Magnetic Field Intensity**
Equipped with military-grade electromagnetic coils and a fully enclosed water-cooling system, this device delivers a stable **20,000 Gauss** ultra-high magnetic field (measured range: 19,800–20,300 Gs). Compared to traditional circular magnetic separators (typically 12,000–15,000 Gs), its magnetic efficiency improves by over 35%, making it ideal for removing micron-level ferromagnetic impurities from **graphite, cathode materials, and anode materials** used in new energy battery production.
**2. Patented Square Structure for Magnetic Leakage Prevention**
Featuring an **octagonal gradient shielding plate** and **modular magnetic pole arrays** , this design overcomes the edge magnetic leakage issues common in circular devices caused by insufficient shielding plate thickness. Third-party tests confirm: the square structure achieves ±3% magnetic flux density uniformity in the working area, with leakage rates below 0.8%—a 6x improvement over circular models (≥5% leakage). This ensures a purification rate exceeding 99.97% for **quartz sand, potassium-sodium feldspar dry powder**, and other non-metallic minerals.
**3. Intelligent Sorting Control System**
- **PID Dynamic Current Stabilization**: Automatically adjusts magnetic gradient and vibration frequency based on particle size (20–400 mesh).
- **7-Inch Industrial Touchscreen**: Real-time monitoring of operating current, temperature, and cumulative throughput (max: 85 tons/hour).
- **Industrial IoT Compatibility**: RS485/MODBUS protocols enable seamless integration with MES systems for cloud-based production data tracking.

### **Industry Applications**
#### **New Energy Battery Material Purification**
For **lithium battery cathode materials (LFP, NCM/NCA)** and **anode materials (artificial graphite, silicon-carbon composites)**, the 20,000 Gs field strength efficiently captures 0.1–5 μm metallic impurities (Fe, Ni, Cr, etc.), helping clients meet the stringent standard of ≤50 ppm magnetic contaminants (per GB/T 30835-2014). This significantly enhances battery cycle life and safety.
#### **Non-Metallic Mineral Processing**
- **Quartz Sand Refinement**: Removes impurities like mica and hematite, elevating SiO₂ purity from 99.3% to 99.99% for photovoltaic glass and semiconductor silica powder.
- **Feldspar Iron Removal**: Reduces Fe₂O₃ content in potassium-sodium feldspar from 0.15% to<0.02%, meeting="" the="">82% whiteness requirement for high-end ceramic glazes.
- **Graphite Upgrading**: Eliminates conductive impurities (e.g., pyrrhotite, ilmenite) from flake graphite, stabilizing carbon content above 99.5% for lithium-ion battery anode applications.
#### **Circular Economy**
Enables >98% recovery of valuable metals from recycled resources like spent lithium battery fragments and solar panel powder, supporting green "production-recycling" industrial chains.
