Larutan: Bubuk Epik MJW 280-L Air Classifier Mill
Solution: Epic Powder MJW 280-L Classifier Mill
The Korean battery manufacturer ultimately selected the latest-generation Epic Powder MJW 280-L classifier mill. This system is specially designed for high-value lithium battery materials such as lithium carbonate (Li₂CO₃), lithium hydroxide, and LFP, integrating ultrafine grinding and high-precision classification into one machine.
Core Equipment Parameters (Based on Lithium Carbonate Operation Test)
- Model: Epic Powder MJW 280-L Classifier Mill
- Grinding + Classification Method: High-speed turbo impact milling + dynamic turbo classifier (integrated system)
- Target particle size: d50 = 7 μm (adjustable range: 2–20 μm)
- Particle size distribution: d97 ≤ 18 μm, extremely narrow (Span < 1.3)
- Measured capacity: 50–70 kg/h (lithium carbonate, moisture <0.2%)
- Main motor power: 7,5 kW
- Classifier wheel speed: Up to 4500 rpm, infinitely adjustable
- Protective gas: Optional nitrogen circulation, completely preventing oxidation or discoloration
- Construction material: Key components made of high-purity alumina ceramics, ensuring zero metal contamination
Actual Performance Results
- Particle size: d50 = 6.98–7.05 μm (Malvern Mastersizer 3000)
- Kapasitas: Stable at 55 kg/h (max up to 120 kg/h)
- Purity: Magnetic metals such as Fe, Cu, Zn < 3 ppm, meeting battery-grade requirements
- Energy consumption: 28% lower than the customer’s previous imported jet mill
- Product appearance: Significantly improved whiteness, no yellowing (thanks to effective nitrogen protection)
