A hopper assembly is a storage and dispensing system designed to hold and control the flow of bulk materials such as powders, granules, or liquids in industrial processes. It typically consists of a funnel-shaped container that directs materials downward through a discharge opening, often equipped with valves, vibrators, or augers to regulate flow. Made from materials like stainless steel, carbon steel, or reinforced plastic, hoppers are used in industries such as agriculture, food processing, pharmaceuticals, and mining. Proper design considerations, including material flow characteristics and discharge mechanisms, ensure efficient operation, prevent clogging, and optimize material handling processes.
