Customer Background and Requirements
The Russian customer is a professional manufacturer in the diatomaceous earth industry, with extremely high requirements for product fineness to meet the needs of high-end applications such as fillers, filtration media, and adsorbents.
Original Requirement Specifications:
- Matériel: Diatomaceous Earth
- Target Capacity: 1 t/h
- Target Fineness (D50): 5.6 μm (micron-level ultrafine powder)
The customer was seeking an efficient ultrafine grinding of diatomaceous earth capable of stable operation at high throughput while ensuring uniform particle size distribution and reasonable energy consumption.
Poudre épique Solution: MQW Series Jet Mill
Based on the customer’s stringent requirements for both capacity and fineness, Epic Powder recommended and supplied the MQW Series Jet Mill (Air Jet Mill).
A jet mill utilizes high-velocity airflow (typically compressed air or inert gas) to accelerate particles, achieving ultrafine grinding of diatomaceous earth through inter-particle collision and friction.
Key Advantages of the MOQ Series:
- Ultrafine Grinding Capability:
The MQW series is specifically designed for ultrafine grinding of ultra-hard, high-purity, or temperature-sensitive materials, enabling stable achievement of micron- or even submicron-level D50 μm. - Non-Contamination:
With no mechanical moving parts inside the grinding chamber, size reduction relies mainly on particle-to-particle collisions, minimizing equipment wear and preventing metal contamination. This makes it particularly suitable for high-purity diatomaceous earth processing. - High Throughput Design:
Optimized for industrial-scale production, the MQW series features a unique airflow design that ensures high hourly capacity while maintaining the required fineness.
Implementation and Results
After installation and commissioning, the equipment was put into operation. Actual performance fully met the customer’s expectations:
| Article | Target Value (Customer Requirement) | Actual Operating Result (Epic Powder MQW) |
|---|---|---|
| Matériel | Diatomaceous Earth | Diatomaceous Earth |
| Capacité | 1 t/h | Stable at 1 t/h |
| Fineness (D50) | 5.6 μm | Stable at around 5.6 μm |
| Pureté | Haut | High (no mechanical impurity contamination) |
| Operational Stability | Haut | Continuous and stable operation, easy maintenance |
