Hosokawa utilizes the Micron Separator MS-1 Air Classifier in the toll processing facility. The MS-1 Air Classifier is a mechanical centrifugal air classifier capable of fine cut points down to 25 µm at rates up to 1,000 lbs/hour. Larger MS Air Classifiers are available for production site installations. The MS-1 Air Classifier is particularly effective when installed in-line with other Hosokawa milling systems include the Mikro Pulverizer. The MS-1 separates oversized materials and can recirculate them directly to the mill feeder for regrinding. This is accomplished by balancing centrifugal forces from the rotor and centripetal forces from the air flow. Adjusting these parameters allows operators to alter the cut point to obtain the desired results.
