Sturtevant Inc. announced the sale of its 5,000th air classifier, more than any other air classifier manufacturer, according to the company. Air Classifier Number One was sold to Reynolds Tobacco Co. of Winston-Salem, N.C., 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 5,000. Number One was capable of cut sizes in the range of 100 to 325 mesh,” according to Sam Rajkovich, director of sales and marketing, Sturtevant. “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 5,000, 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, the company said.
Sturtevant supplied Number 5,000 to 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,” said Rajkovich.
