Milling Systems

Air Classifier Mill

The Air Classifier Mill (SDF Series) is a dry classification solution designed for precise separation of fine and coarse powders across a wide range of materials. Utilizing a horizontal centrifugal classifier rotor and dual air intake, the system enables accurate control of particle cut points while maintaining consistent product quality. Its robust, compact construction and low-vibration operation make it well suited for continuous industrial processing and integration with upstream grinding equipment.

Frequently Asked Questions

What does an air classifier mill do?
An air classifier mill separates material by particle size using controlled airflow and centrifugal forces. Fine particles are conveyed out of the system as finished product, while oversized particles are discharged separately or returned for additional processing.
What particle size range can the Air Classifier Mill achieve?
Depending on the model and material characteristics, the Air Classifier Mill can classify powders across a broad fineness range, with cut points reaching down to approximately 10 microns (d97) and extending into coarser size ranges for high-capacity applications.
What industries and materials is this air classifier mill used for?
It is commonly used for mineral and chemical applications, including calcium carbonate, lime, clays, oxides, carbonates, graphite, and other fast-flowing powders with varying particle shapes and densities.
Can this air classifier be paired with other milling equipment?
Yes. The Air Classifier Mill is frequently installed downstream of open-cycle grinding mills to remove fines and recirculate coarse particles, improving overall process efficiency and particle size control.
Where do HaF milling systems come from?
HaF partners with STM Microtec to deliver advanced milling systems, combining proven mill technology with HaF’s expertise in integrated ingredient handling solutions.
