Size Reduction and Air Classification:
Engineered Material Processing Equipment
Time-Tested – Proven Success

Sturtevant Inc. is a family-owned manufacturer of material processing equipment including crushers, fine grinders and air classifiers.  Since 1883, the company has provided processing solutions to the chemical, pharmaceutical, food and mineral powder processing industries worldwide.



Interchangeable Rotors for Trona and Sodium Bicarbonate

Specifically designed for the rigors of dry sorbent processing, the NEW Sturtevant Simpactor 6C- 30 FGD is easily convertible for the unique properties of Trona and Sodium Bicarbonate.

Dry Sorbent Injection Systems have proven to be highly effective at reducing SOx emissions in small to mid-size coal fired power plants in comparison to wet systems. Dry Systems equipped with a pulverizer, such as the Sturtevant Simpactor 6C-30 FGD, typically cost less to operate because they use up to 30% less sorbent; benefitting from a corresponding reduction in disposal costs. The process is also preferable to existing wet systems due to the elimination of environmentally hazardous and costly settling ponds..

Air Classifiers

Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment. All three Sturtevant air classifiers offer durable construction, as well as time- and energy-saving advantages.

Micronizer® Jet Mill

The Sturtevant Micronizer® is a jet mill (fluid energy mill) employing compressed air or gas to produce particles less than one micron. Inside the Micronizer, precisely aligned jets create a vortex. Material is fed into this vortex along an engineered tangent circle and accelerates.

High-speed rotation subjects the material to particle-on-particle impact, creating increasingly smaller fines. While centrifugal force drives large particles toward the perimeter, fine particles move toward the center where they exit through the vortex finder

Powderizer® Air Classifying Mill

The Sturtevant Powderizer® is a “classifying impact mill” capable of reducing powders down to 5 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 Powderizer’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 chemical, food, minerals and others.

Sample Testing and Evaluation Procedures

Sturtevant maintains a Customer Test Center where customers may have their material processed through pilot scale equipment.   Customers are welcomed and encouraged to be present to observe the processing.

Sturtevant testing is done on a scheduled basis. To arrange for a mutually convenient time, please contact the Sales Department at 1-800-992-0209. Prior to scheduling a test, the following information is needed:

-Completed MSDS (Material Safety Data Sheet)
-Sturtevant Information Request Form
-Approval from Sturtevant’s Safety Committee with a MATERIAL AUTHORIZATION NUMBER to ensure safe handling and processing of your material
-Purchase order to cover the estimated cost of the test
