The customer is a well-known sports nutrition manufacturer in Serbia, specializing in creatine monohydrate powder. As the European market increasingly demands finer deeltjesgrootte and faster solubility, the customer’s existing mechanical milling equipment could no longer meet the requirement of D90 ≤ 80 μm. Traditional milling also caused localized overheating, purity degradation, and unstable particle size distribution between batches.
Requirement Analysis
- Target particle size: D90 ≤ 80 μm (ideally controlled between 70–80 μm)
- Materiaaleigenschappen: Creatine monohydrate contains one crystal water; it is highly heat-sensitive, and temperature rise must be strictly controlled during milling
- Capacity requirement: 200–400 kg/h per line
- Purity requirement: No metal contamination during milling; finished product purity ≥ 99.9%
- Energy & environmental standards: Must comply with EU energy efficiency and dust emission regulations
Selectie van apparatuur
After multiple online and on-site technical discussions, we recommended the customer Episch poeder’s flagship model:
MQW Jet Molen System (equipped with a high-precision lucht classificator).
Equipment Advantages
- No mechanical grinding:
There are no moving parts inside the milling chamber, effectively preventing mechanical contamination and ensuring high product purity. - Temperature control:
The milling medium (usually compressed air or nitrogen) undergoes isentropic expansion and cooling during jetting, offsetting frictional heat — ideal for heat-sensitive materials. - Precise classification:
The built-in classifier continuously separates particles that meet the target fineness and recirculates coarse particles for further milling, ensuring final product D90 = 80 μm is precisely achieved.
On-Site Operation Data
- Raw material: Creatine monohydrate (initial D90 approx. 250–350 μm)
- Working medium: High-purity nitrogen (closed-loop system)
- Milling pressure: 0.6–1 MPa
- Classifier speed: 28–32 Hz
- Actual capacity: 350–420 kg/h
- Particle size distribution: D50 = 18–22 μm, D90 = 72–78 μm (stable and compliant)
- Specific energy consumption: approx. 135–145 kWh/ton
- Product yield: ≥ 99.3%
- Moisture variation: ≤ 0.05% before/after milling (crystal-water structure perfectly preserved)
