Also known as: Pulveriser, Micronizer and Grinder.

Size reduction is achieved in a static circular housing using a high speed rotational beater plate.

·         The rotating beater creates airflow to pneumatically convey the product into the milling chamber.

·         The beater then imparts a force on the product to fracture the particles into smaller particles in the milling (or grinding) zone.

·         The high velocity airflow induced in the machine sweeps the milling chamber with product further abrading the particles and reducing their size.

·         Once the product particles have reached the end of the milling chamber they are either pneumatically conveyed into a dust collector as finished product or passed through an optional dynamic air classifier to separate the particles for re-milling.

·         The Dynamic Air Classifier is driven by an independent drive motor but forms an integral part of the complete Mill.

·         Beater plates are available in sizes 250mm, 500mm, and 750 mm diameter.

Whilst the primary function of an air swept mill is to reduce particle size, additional functions can be incorporated:

·         Cooling - when chilled air is used for heat sensitive products.

·         Flash drying - when high inlet temperatures are used.

Applications
