In the nutraceutical and pharmaceutical industries, calcium citrate is a highly bioavailable calcium supplement widely used in tablets, capsules, and functional foods. Achieving a fine and uniform particle size is critical for improving dissolution rate, bioavailability, and product consistency. Epic Powder’s MQP series spiral jet mill delivers exceptional performance in processing this heat-sensitive material without contamination or thermal degradation.
Project Overview
A leading calcium supplement manufacturer approached Epic Powder seeking an efficient solution to micronize calcium citrate. The goal was to produce a superfine powder with excellent flowability and rapid dissolution properties while maintaining high throughput.
Solution: MQP Spiral Jet Mill
The customer selected the MQP spiral jet mill (disc jet mill), known for its simple structure, contamination-free grinding, and suitability for heat-sensitive and low-melting-point materials. Compressed air accelerates particles to sonic or supersonic speeds inside the flat grinding chamber, where they collide and fracture. Qualified fine particles are carried out by the airflow, while coarser ones continue to be ground—ensuring a narrow particle size distribution.
Grinding Results
| Parameter | Result | Benefit |
|---|---|---|
| Target Material | Calcium Citrate | Heat-sensitive, food-grade |
| Final Particle Size | D90 = 17.2 μm | Superior bioavailability |
| Throughput | 260 kg/h | High-volume production |
| Grinding Technology | MQP Spiral Jet Mill | Zero contamination & low heat |
The final powder exhibited excellent dispersibility, no agglomeration, and consistent quality batch after batch. Compared to traditional mechanical mills, the MQP jet mill offered lower energy consumption per ton, zero metal contamination, and minimal heat generation—ideal for preserving the chemical integrity of calcium citrate.
