Air classification very often supplements micronization or is used in place of Micronization. The NETZSCH-CONDUX CFS-HDS series air classifier provides the sharpest separation of fines to d50 ~ 1 µ. High dispersion effectively separates particles in near proximity to the classifier wheel without intermixing of fine or coarse material with new feed material. You can expect steep particle size distributions and high yield. Various sanitary executions available include closed loop inert gas, pressure shock resistant construction, and high strength ceramic materials for metal contamination free processing such as yttrium stabilized zirconium oxide classifier wheel and vane ring or stainless steel parts with surface finish of Ra = 0.6 µ. All product contact parts can be sterilized with autoclave (depending on machine size).
