Funnel Body: Inlet Diameter 200-1000 mm, Wall Thickness 2-10 mm

Component Specifications

Definition

The funnel body is a critical component in hopper funnel systems, designed to facilitate the controlled discharge of granular, powdered, or liquid materials. It typically features a tapered geometry to prevent material bridging and ensure consistent flow rates. Engineered to handle specific material characteristics, it interfaces between the storage hopper and conveying or processing equipment, optimizing material transfer efficiency and minimizing waste or spillage.

Working Principle

The funnel body operates on gravity flow principles, utilizing its tapered design to direct materials downward. Whether the material actually flows is decided by the outlet size and the wall slope, not by any gain in velocity: the outlet must be larger than the critical arching dimension for that material, and the walls steep and smooth enough for its wall-friction angle, otherwise the converging section is exactly where a stable arch forms and blocks discharge. It may incorporate features like vibration or aeration to assist with difficult-to-handle materials, maintaining flow continuity in industrial processes.

Materials

Commonly constructed from stainless steel (e.g., SS304, SS316 for corrosion resistance), carbon steel, or food-grade plastics (e.g., polyethylene, polypropylene). Material selection depends on application requirements such as hygiene, abrasion resistance, and chemical compatibility.
