Air classifiers are used to separate particles in dry powder. Like screens, you have a plus fraction (Coarse) and a minus fraction (fines). Unlike screens which typically start to blind around 44um (325 mesh), air classifiers can be used to separate particles in the sub-micron range.
The MICRO-SEAL® makes the MICRO SIZER® system superior to other classifiers by maximizing the percentage of recovery of fine particles compared to the percentage available. Providing solutions for all your fine product needs continues to be the number one priority at Progressive Industries, Inc.

Trough Mill
The newly patented Trough Mill® manufactured by Progressive Industries, Inc. provides not only the typical “stirring” action produced by other media mills but also includes compression and contraction actions as well. These added actions help increase grinding and through-put tonnage, which relates to a lower hp/ton cost. Available in multiple sizes, the Trough Mill® can be used in conjunction with a Micro Sizer® Air Classification System for a closed loop system, or it can be used as a stand-a-lone mill. Progressive Industries, Inc. is available to help you with your fine/ultra fine product needs.
