Used hoppers are designed for the storage, handling, and controlled discharge of bulk materials across food processing, plastics, chemical, agricultural, and industrial applications. Inventory may include carbon steel, stainless steel, and aluminum hoppers in a wide range of capacities and configurations, including cone bottom, pyramid, live bottom, and surge bins, as well as mass flow hoppers, funnel flow hoppers, weigh hoppers, and loss-in-weight feeders. Common features include screw, auger, vibratory, and belt discharge systems, along with airlock valves and integrated conveying equipment. Equipment from manufacturers such as Anderson Dahlen, Doyle, Vac-U-Max, and Rietz is commonly available, along with K-Tron, Flexicon, Hapman, Acrison, and Coperion. These units are used for handling powders, granules, flakes, and other bulk solids in both batch and continuous operations.
