GreyStone washing, classifying and dewatering equipment traces its beginnings back to 1956 in Benton, Kansas, with the philosophy of "Build it the way it should be!" The product line was moved to Columbus, Nebraska, in 1981 and continued to be marketed under the name of L.B. Manufacturing. The name was changed to GreyStone in 1988.
