Star Feeder – Precision Flow Control for Bulk Material Handling

Star feeders are essential components in bulk material handling systems, designed to regulate the controlled discharge of granular and powdered materials while preventing unwanted airflow between feeding and discharge zones. They are especially effective in systems operating under pressure, vacuum, or gravity.

These feeders play a critical role in pneumatic conveying systems and are widely used in the handling of free-flowing materials. Depending on the material characteristics, star feeders can be manufactured with cast iron bodies, stainless steel construction, or specially coated surfaces for enhanced wear and corrosion resistance.

Applications

• Regulating material flow from silos, bunkers, and mixers
• Ensuring pressure integrity in pneumatic transfer systems
• Used extensively in cement, mining, and chemical industries

Key Features

• Airlock Function: Prevents air leakage between feed and discharge zones
• Material Versatility: Compatible with fine powders, grains, and granules
• Customizable Body Types: Available in cast iron, stainless steel, or coated for specific material compatibility
• Consistent Discharge: Provides smooth, metered flow into processing or conveying systems

Star feeders are an indispensable solution for operations requiring consistent material control and airtight separation, enhancing system efficiency and operational safety.
