Fast Facts
Flexible equipment:
Our equipment enables us to offer different types of particle size reduction of your API depending on your desired particle size.
State-of-the-art milling suites:
Our Material Science Centre houses four independent processing suites.
.
Expert teams:
Our specialists will help you develop the particle size reduction strategy best suited to your material and requirements.
Full visibility:
CCTV monitoring enables customers to view milling operations remotely.
State-of-the-art equipment:
We can utilise mechanical milling, micronisation technology, or a combination of both to achieve your required particle size distribution.
Our mechanical milling capabilities enables us to achieve a particle size down to 30 microns. Our equipment offers the flexibility to support different modes of milling, and our team will help determine which approach, or combination of approaches, will achieve your particle size requirements.
Our mechanical milling equipment includes:
- Two Frewitt Fredrive units with interchangeable heads. One of our units spans three floors of the Material Science Centre and offers containment up to OEB 4. We can utilise these units for hammer, knife, conical, and sieve milling based on your project requirements.
- Fredrive Lab for milling development that supports hammer, knife, sieve, and pin milling.
- Fitzpatrick mill that supports hammer and knife milling.
When an even smaller particle size distribution is required, we can utilise micronisation technology. Micronisation of an API, or spiral jet milling, enables us to achieve a particle size down to 2 to 5 microns.
Our micronisation equipment includes:
- Sturtevant 1” Microniser enables us to micronise small amounts of material, from 50 to 500 grams, at a throughput rate which is governed by the particle characteristics of the supplied API.
