Material Reservoir/Hopper Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A material reservoir or hopper is a precision-engineered container designed for temporary storage and controlled discharge of bulk materials in industrial deposition and feeding mechanisms. It ensures consistent material flow, prevents bridging or rat-holing, and maintains material quality through features like agitation, level sensors, and discharge control systems.

Working Principle

Gravity-fed storage with controlled discharge through gates, valves, or augers; may include vibration, agitation, or fluidization to maintain material flow and prevent compaction or segregation.

Materials

Stainless steel (AISI 304/316), carbon steel, food-grade polymers (HDPE, PP), or aluminum; selected based on material compatibility, corrosion resistance, and hygiene requirements.

Technical Parameters

Capacity 50-5000 liters
Discharge Rate Adjustable 0.1-100 kg/min
Angle of Repose ≥60°
Outlet Diameter 100-500 mm
Temperature Range -20°C to 150°C
Operating Pressure Atmospheric to 0.5 bar

Standards

ISO 9001, DIN 28018, FDA 21 CFR Part 117
