Profile: Sturtevant, Inc. is a manufacturer of material processing equipment including crushers, fine grinders and air classifiers. We provide processing solutions to the chemical, pharmaceutical, food and mineral powder processing industries. We custom engineer units suited to the widest range of size reduction applications from large coarse particle crushers to the patented sub-micron Micronizer®. The Sturtevant Micronizer® is a jet 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. The Sturtevant Powderizer® is a classifying impact mill capable of reducing powders down to 5 microns. The Powderizer's flexibility of operation allows it to easily process a multitude of product categories requiring particle size reduction for a broad range of industries including chemical, food, minerals and others. Our 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 an effective means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment.
