Air Classifiers

Sturtevant: Quality for the Generations

The SuperFine
Ideal for separations at 44-5 microns.

The Side Draft (SD)
High-efficiency separations.
Versatile, variable-speed control to change fineness online.

Each provides unique benefits, backed by maximum performance and Sturtevant durability to deliver customized solutions for your most exacting needs.

Sturtevant air separators 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, when used in conjunction with grinding equipment, for increasing productivity. All three Sturtevant air classifiers offer durable construction and other time- and energy-saving advantages, including:

• Capability to process an extensive range of dry materials
• Higher capacity and finer separations than screeners
• Simple construction, low maintenance, easy-to-use controls
• Dial-in external fineness controls: no system shutdown to change
  products
• Maximized wear-resistance for abrasive materials in special
  applications
• Easily modified for water cooling, air cooling or drying of product
• Safe classification for heat-sensitive materials
• No screens to wear, block, or tear
