Rotary Airlock Feeder

Product Details:

Precision Bulk Material Feeding with Airtight Sealing for Controlled Pneumatic Conveying

The Rotary Airlock Feeder is a critical component in bulk material handling systems, engineered to provide consistent volumetric feeding of powders, granules, and particulate solids while maintaining an airtight seal between different pressure zones. This device is designed to optimize the flow of dry bulk materials from hoppers, bins, or silos into pneumatic conveying lines or downstream processing equipment, ensuring efficient material transfer with minimal air leakage.

Constructed from robust stainless steel (SS 304/316) or mild steel, the rotary feeder features a precision-engineered rotor with multiple vaned pockets that rotate within a tight tolerance housing, creating an effective airlock barrier. The rotor pockets capture fixed volumes of material and deliver them at a controlled rate, which can be adjusted through variable speed drives to match process requirements.
