Rotary Feeder Improves Material Introduction Consistency

Airsys Valves announces a new series of rotary feeders designed specifically for pneumatic conveying of dense materials, such as fine powders used in chemical and pharmaceutical processing, food and bakery processing, plastics, and milling. The Aero-Flow Series of rotary feeders from Airsys Valves provides highly efficient, air-assisted, material introduction to pneumatic conveying systems.

Aero-Flow rotary feeders use a proprietary, dual-induction endplate design to introduce pressurized air from both endplates into the rotor pockets carrying process material. When high bulk density material is mixed with air it is more effectively released from the rotor pockets, and is more efficiently introduced to the pneumatically conveyed material flow.
The dual-induction design speeds the material fluidization process, which improves material consistency and optimizes feeder energy consumption when compared to conventional, single-induction feeder designs. Additional energy efficiency is provided by an optional Airsys variable frequency drive, which modulates the feeder drive speed and reduces power requirements based on the fluctuating performance needs of the system.
Housings for Aero-Flow feeders are available in cast iron and 304 or 316 stainless steel; in either 17-1/2 in or 21-1/8 in heights. All housings are cast in North America to ensure superior strength in the composition and solidification of the housing's metallurgy. The Aero-Flow Series feeders provide optimal service in applications with pressure differentials up to 15 PSIG and elevated temperatures to 500 degrees. The Aero-Flow Series 10-vane rotor is precision machined with beveled vane tips and sides. Other Aero-Flow rotor configurations include Teflon-coated, and adjustable-tips. Adjustable rotor tips are available in hardened steel, or stainless steel. Rotor housing interior surface coating options include hard chrome, tungsten, and Teflon.
