ACS Valves’ new rotary feeder, dubbed the Aero-Flow, is designed for pneumatic conveying of dense materials such as fine powders used in chemical and pharmaceutical processing, food and bakery processing and plastics and milling.

ACS’ rotary feeder for pneumatic conveying

ACS Valves’ Aero-Flow rotary feeder.

According to ACS, Aero-Flow rotary feeders provide highly efficient, air-assisted, material introduction to pneumatic conveying systems.

Aero-Flow feeders use a proprietary, dual-induction endplate design to introduce 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.

The dual-induction design speeds the material fluidisation process, improves material consistency, and optimises feeder energy consumption when compared to conventional, single-induction feeder designs.

Further energy efficiency is provided by an available ACS variable frequency drive to modulate the feeder drive speed and reduce power requirements based on the fluctuating performance needs of the system.

ACS’ rotary feeder is available in cast iron, and 304 or 316 stainless steel in either 44cm or 54cm heights. They are suited to applications with pressure differentials up to 15 PSIG, and elevated temperatures to 260ºC.

The Aero-Flow Series 10-vane rotor is precision machined with bevelled 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.
