Over the past five decades the Vorti-Siv has grown and expanded continuously. New sieving and filtration products, along with the development of new wet and dry screening technologies, drove expansion. By 2000 manufacturing space increased to include fabrication, fine metal polishing and warehousing. In 2010, the company purchased Circular Screens Inc. located in Massillon, OH. A 7,500 sq. ft. building addition was completed in February 2011 to house the new acquisition. Circular Screen Division is now able to provide new or re-screen many types of round and rectangular screen elements.
