1. Aperçu du projet
The client is a prominent Indian chemical manufacturer specializing in high-end pigments for coatings, inks, and plastic masterbatches. To compete in the global market, they needed to upgrade their production technology to achieve superior color strength and dispersibility by implementing an advanced Ultrafine Pigment Grinding process to reduce particle size to a precise sub-10-micron range.
2. Core Challenges
- Precision Requirements: A strict target of d99 μm with a narrow particle size distribution (PSD).
- Material Sensitivity: Pigments are often heat-sensitive and prone to sticking, requiring a solution that prevents thermal degradation and equipment clogging.
- Purity Standards: Zero tolerance for metallic contamination to maintain the vibrancy and chemical integrity of the organic/inorganic pigments.
- Small-Scale Efficiency: A balanced throughput of 50kg/h for high-value batch production.
3. La solution : Poudre épique Spiral Jet Mill System
Epic Powder designed a customized, compact ultrafine pigment grinding line centered around the Spiral Jet Mill (Disc-type Jet Mill) technology.

4. Project Results
Following successful installation and commissioning at the client’s facility in India, the production line achieved the following:
- Consistent Micronization: Real-world testing confirmed a stable d99 between 7.1μm and 7.3μm.
- Enhanced Color Performance: Due to the uniform particle size, the pigment’s tinting strength increased by 15-20% compared to their previous milling method.
- Low Operating Cost: Optimized nozzle geometry reduced air consumption, making the 50kg/h scale highly economical for high-value specialty pigments.
Client Feedback:
“Epic Powder’s Spiral Jet Mill delivered exactly what we needed. The precision in particle size control and the ease of cleaning between batches have significantly improved our production efficiency and product quality.”
