Sturtevant Side Draft Air Classifier
Available from Sturtevant Inc
By air separating Flyash at 325 mesh (45 microns), product quality can be consistently achieved by controlling the fineness and by reducing the LOI carbon content by 50% or more to a level that is tolerable for use in cement, as a filler for land reclamation, soil improvement, lightweight aggregates, and agricultural uses.
Everyday, Sturtevant Air Classifier installations not only produce a saleable Flyash product, but also reduce the amount of Flyash that would otherwise fill up landfills by 50%. In addition, these systems save disposal costs and contribute to saving our environment.
Side Draft™ Air Classifiers: For power plants where flyash output or desired flyash market specifications may vary, the SD Side Draft™ Air Classifier incorporates our state-of-the-art design and produces better efficiencies with more versatility than the Whirlwind© Classifier. By using an external fan to generate the system air flow, the speed of the independently driven rejector cage can be adjusted according to various feed characteristics and thus, maintain consistent product fineness and quality. The feed is conveyed into the Air Classifier by gravity and the coarse exits form the bottom of the Classifier by gravity. The fines are pneumatically conveyed through the rejecter cage and collected in a product dust collector. The SD also comes with alumina ceramic liners for maximum wear protection.
