Jet Milling and Air Classification: The Secret to Ultrafine Particles

Webinar hosted by: Horiba Scientific in Association with The American Ceramic Society

Tuesday, May 17, 2022; 1:30 p.m. Eastern US time


Grinding has a wealth of processing options to choose from depending on incoming and final particle size, material to be ground, volumes, and cost. Closely coupled with many grinding processes is a classification step where material that is not in the desired size range is removed for recycling or waste. 

An outline of grinding options will be discussed with advantages and disadvantages of different processes being considered. The focus of this presentation will be on jet milling and air classification. Starting with a process description, you will see comparisons to other grinding processes for different types of materials and their grinding characteristics, as well as examples showing how to optimize jet milling and air classification. Materials in this presentation will include ceramics, glasses, polymers, and carbon blacks as they are used in specialty chemical, battery, and additive manufacturing applications.

AVEKA was founded in 1994 as a spin off from 3M as a particle processing company. The company has focused on developing and manufacturing powder materials with novel and value-added attributes for the food and industrial markets. Main services provided are drying, grinding, blending, agglomeration and coating processes. AVEKA experts will assist in finding the best processing method for an application.
