Venturi eductors convey dust from baghouse to dumpster, leaving old dumping method in the dust
Dumping baghouse dust left plant grounds dirty, so a foundry switched to pneumatic conveying.
Aarrowcast Inc., a foundry in Shawano, Wis., makes gray and ductile iron castings. Sand is used to form molds in the casting process. Although much of the sand can be reused, each batch must contain a certain percentage of new sand. Therefore, new sand continually displaces spent sand. Dust created by this process is collected by an outdoor baghouse.
