Product Description
Seri QLDJ adalah jet mill — crusher paling halus di katalog kami, menghasilkan powder 2–150 μm (jauh lebih halus dari crusher mekanik lain: WFJ ~32 μm, BIV ~125 μm). Mekanisme: material di-fluidisasi dengan compressed air 0,65–0,95 MPa dan dibenturkan partikel-on-partikel tanpa kontak blade → zero contamination dari wear blade. Cocok untuk pharma micronization, cosmetics ultra-fine pigment, ceramic. 3 model, 300/400/630.
Jet mill vs crusher mekanik
| Tipe | Mekanisme | Output |
|---|---|---|
| QLDJ jet mill (#42) | Compressed air + particle attrition (no blade) | 2–150 μm (ultra-fine) |
| WFJ (#25) | Rotor blade + cyclone | ~32–250 μm |
| Pulverizer-BIV (#27) | Rotor blade + bag | ~125–850 μm |
Pilih jet mill jika: butuh ultra-fine (400 mesh) yang tidak bisa dicapai mechanical; concern contamination wear blade (pharma API, food/cosmetic premium); material heat-sensitive (grinding minimal panas).
Cara kerja — fluidized-bed particle attrition
- Material pre-ground (~100 mesh) masuk chamber.
- Nozzle udara 0,65–0,95 MPa men-fluidisasi material.
- Partikel saling membentur kecepatan tinggi → pecah (tanpa blade/hammer kontak).
- Grading wheel (4000–8000 RPM) memisahkan by ukuran: halus in-spec ke cyclone; besar re-grind.
- Output ultra-fine dikumpulkan cyclone + bag filter.
Kelebihan: zero blade contamination, cold grinding (udara expansion → chamber <50°C), particle size distribution sempit, minimal maintenance, GMP-friendly. Kekurangan: total power tinggi (90–360 kW termasuk compressor), investasi mahal, capacity per kW lebih rendah, feed harus pre-ground ~100 mesh dulu.

| Grading wheel power | 4 kW | 7,5 | 11 kW |
| Grading wheel speed | 8000 r/min | 6000 | 4000 |
| Air flow | 10–13 m³/min | 20–25 | 40–50 |
| Handling ability | 30–250 kg/jam | 100–500 | 200–1000 |
| Total system power | 90–110 kW | 160–180 | 300–360 kW |
Cara memilih
- Pilot/menengah (30–250 kg/h): QLDJ-300 (finest 2–100 μm, 90–110 kW).
- Menengah-besar (100–500 kg/h): QLDJ-400 (5–120 μm, 160–180 kW).
- Besar/industrial (200–1000 kg/h): QLDJ-630 (6–150 μm, 300–360 kW).
Butuh compressed air supply besar (10–50 m³/min) + pre-grinding upstream (~100 mesh). Total power tinggi — pastikan supply listrik memadai.
Penggunaan umum
- Pharma micronization (API, inhalable powder), cosmetics (pigment/talc ultra-fine), ceramic raw material, pewarna premium, food premium (matcha, spice ultra-fine), battery material.
FAQ
- Kenapa jet mill lebih halus? Particle-on-particle attrition + air classification → 2–150 μm, tidak bisa dicapai blade mekanik.
- Zero contamination? Tidak ada blade kontak material — cocok pharma GMP.
- Heat-sensitive? Cold grinding (udara expansion) — chamber bisa <50°C.
- Perlu pre-grinding? Ya — feed harus ~100 mesh; material kasar butuh crusher upstream.
- Kenapa power tinggi? Include compressor besar untuk compressed air.
- Melayani B2B & seluruh Indonesia? Ya.
