Rotary feeder introduces powders to pneumatic conveying systems
ACS Valves’s Aero-Flow series of rotary feeders is designed for pneumatic conveying of dense materials such as fine powders. The feeders use a proprietary, dual-induction endplate design that introduces pressurized air from both endplates into the rotor pockets carrying process material. The high bulk density material, when mixed with air, is more effectively released from the rotor pockets and is more efficiently introduced to the pneumatically conveyed material flow.
While single-induction designs have only one source of pressure-conveying air, the second air source in the dual-induction functionality is intended to improve aeration and flowability of products with sticky material characteristics. The feeder is designed to integrate with most pharmaceutical pneumatic conveying applications, and the dual-induction design’s applications are appropriate for applications in which the material’s characteristics make efficient material transfer challenging. The feeder is available with 304 and 316 stainless-steel cast housing for sanitary applications.
