FCM Classifier Mill

CLICK TO ENLARGE

The Sturtevant FCM is a classifying impact mill capable of reducing powders down to 10 microns. It is fast becoming the workhorse in particle size reduction applications due to its combination of impact milling and air classification technologies in a single unit. The FCM’s flexibility of operation allows it to easily process a multitude of product categories requiring efficient and economical particle size reduction for a broad range of industries including pharmaceutical, food, chemical, mineral and others.

How-it-Works

Sturtevant FCM Classifier Mills are designed to provide size reduction with an integrated classifier to insure the desired product is achieved. The mill’s operating principle is mechanical impact size reduction which minimizes the operating energy costs. The internal air flow then leads the material to the integrated air classifier to separate the desired product from the material that is still too large. The Classifier operating principles balance centrifugal force and drag force to generate a high precision method of classifying particles according to size and density. The oversize particles are then automatically returned to the milling chamber until they are reduced to the desired size.
