fine mesh powder screen Archives | Solutions In Motion

Jan 24, 2021 · Many times the enduser needs finer powder to create the intrie parts they are producing. This powder is typically said to be +20 25 micron powder. We are also told this powder is classified through an air classifiion process. The process, while quick and relatively easy, leaves a powder that is not always what it is claimed to be.

AF Air classifier

Before being discharged, the coarse material is rinsed intensively in a spiral flow taken from the secondary air stream to remove any last fine powder, this step improves the precision of cut and increases the fine powder yield. The dry classifiion is achieved based on the size, shape and density of particle, the classifier can be used with ...
