Air classifier mill: Does it separate by weight or particle size

A common misunderstanding among industrial crusher buyers is that an air classifier mill separates particles by weight — if your material is lighter, it gets blown away. In reality, air classification works by particle size, not density. The classifying wheel uses centrifugal force to throw out larger particles while finer powder follows the airflow through.

Take a carob grinding project in Chile as an example: carob seeds are lighter than the pulp, leading many processors to worry that the seeds will be lost, causing an uneven final product. But as long as both are ground to the same size range inside a stainless steel crusher, their weight difference has no impact on uniformity — the classifier only cares about particle size.

The takeaway? Don't let misconceptions about airflow stop you from choosing the right powder grinding machine or food grinder for your process. When in doubt, ask a professional manufacturer for answers
