Sturtevant Reaches Air Classifier Milestone


Particle size reduction and air separator manufacturer sells 5,000th Air Classifier



Sturtevant, Inc., one of the world’s largest suppliers of air classifiers and related equipment, sold and installed, is proud to announce the sale of its 5,000th Air Classifier, more than any other Air Classifier manufacturer. Air Classifier Number One was sold to Reynolds Tobacco Co. of Winston-Salem, NC and shipped on Sept. 18, 1919. This early design still has features recognizable today in Sturtevant’s Whirlwind® Air Classifier including an internal fan.



“Significant changes have taken place between the shipment of Serial Number One and Number Five-Thousand. Number One was capable of cut sizes in the range of 100 to 325 mesh” according to Sam Rajkovich, Director of Sales and Marketing. “Number One was innovative for its time, the first internal fan classifier with sharp cut point classification and recirculation. The early predecessor of the Whirlwind® Classifier we offer today.”



Number 5000, a SuperFine Air Classifier is a quantum leap in technology with cut points as low as 3 micron it is a cutting edge, ultra-high efficiency classifier.



Sturtevant is proud to supply Number 5000 to its valuable partner Imerys, known as “the world leader in mineral-based specialty solutions for industry.”



“Sturtevant and Imerys have been partnering for many years so it is fitting that they helped us reach this amazing milestone. On behalf of the employees and the Sturtevant family, we are all very excited to reach this goal and we are proud that machines in over 150 countries bear the Sturtevant name,” says Rajkovich.
