FUNCTIONAL PRINCIPAL
Material is introduced into the jet mill through a controlled feeding system. Compressed air or gas is directed through precisely arranged nozzles, accelerating particles inside the grinding chamber.
What is Static Classification?
As particles collide with each other at high velocity, they fracture into smaller particles. Fine particles are carried out of the mill and collected, while larger particles continue circulating until reduced to the target size range.
What is Active Classification?
Active jet milling classification uses a high-speed classifying wheel to precisely control the final particle size during the milling process. As particles are reduced in the grinding chamber, they are carried by the process gas toward the rotating classifier.
Fine particles that meet the target size pass through the wheel and exit the mill, while larger particles are rejected by the centrifugal force of the classifier and returned to the grinding zone for further size reduction. This active classification method provides tighter control over particle size distribution and allows the cut point to be adjusted by changing the classifier wheel speed.
In comparison, static classification relies on fixed geometry and airflow patterns within the milling chamber to separate fine particles from coarse particles, without a moving classifier. Static classification is simpler and has fewer mechanical components, while active classification offers greater precision, flexibility, and control for applications requiring a narrow and consistent particle size distribution.

RENTAL OPTIONS AVAILABLE
Renting gives your team the ability to test particle size reduction directly in your own laboratory, using your actual material, process conditions, and analytical methods. This allows you to evaluate performance, confirm target particle size, study product recovery, and determine whether jet milling is the right solution before making a capital equipment purchase.
Rental units are especially useful for short to long term projects, feasibility studies, process development, and customer trials where flexibility and speed are important. By testing in-house, your scientists and engineers can better understand how the material feeds, mills, and collects, while reducing project risk and helping justify the correct equipment configuration for future production needs.
