FAQs
What makes the Air Classifying Mill ideal for heat‑sensitive materials?
Continuous airflow and independent classifier control limit thermal exposure while delivering tight PSDs for aroma‑rich spices, cocoa, APIs, and botanical actives.
Can MACM produce narrow particle distributions for regulated pharma?
Yes. MACM provides fine PSDs with d97/d50 tuning, hygienic construction (SS316L options), and documentation aligned with cGMP.
Is the system compatible with inert gas operation and explosion safety?
Available inerting and ATEX‑aligned configurations support oxygen‑sensitive materials and combustible dust environments.
How does MACM compare to a mill plus external classifier setup?
MACM integrates grinding and classification, reducing footprint, simplifying controls, and stabilizing cut‑point consistency.
Can MACM integrate into existing lines?
Absolutely—MACM connects with pneumatic conveying, cyclones/filters, sifters, blenders, and packing lines for a seamless upgrade.
Achieve Tight Particle Control with MACM
Air Classifying Mill (MACM) allows you to control particle size with accuracy, not compromise.
Integrated classification eliminates over-grinding while improving consistency, efficiency, and throughput.
