As demand for more stringent material specifications grows and quarries progress further into their reserves, the need to wash aggregate materials increases. In 2014, Superior acquired Greystone Inc. Since then, we’ve been supplying wet processing solutions at our Columbus, Nebraska plant dedicated to manufacturing equipment to meet the needs of the market. With the expansion, we inherited an experienced team of engineers and manufacturing personnel, along with a treasure of intellectual property to allow our customers to wash and classify their bulk materials to an impeccable spec.
