An air classifier mill combines a mechanical impact mill with a dynamic air classifier. Ideal for large-volume continuous processing, the mill is one of today’s
most widely used grinding machines for reducing dry fine chemicals, food products, and other materials.After describing the air classifier mill’s applications,
operation, and common variations, this explains how you can adjust the mill’s operation to control the final product’s particle size
s ize reduction equipment for processing dry bulk materials is available in several types and can produce
coarse, medium, fine, or ultrafine particles. This concentrates on air classifier mills, which produce fine particles with a nominal top size of 45 microns or finer, depending on the material.
An air classifier mill applies impact grinding and air classification in one step. The mill uses airflow to convey feed
material to the mill’s grinding chamber, classifies the material into fine and coarse fractions, recirculates the coarse
fraction for further grinding, and conveys fine particles out of the mill, all in one continuous operation.
