ACS Valves: Rotary Feeder Improves Material Introduction Consistency

ACS_main.jpg

ACS Valves 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 ACS Valves provides highly efficient, air-assisted, material introduction to pneumatic conveying systems.

The ACS Aero-Flow Series of rotary feeders uses 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 Aero-Flow Series dual-induction is designed to speed the material fluidization process, improve material consistency, and optimize 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 Aero-Flow Series feeder housings are cast in North America to ensure strength in the composition and solidification of the housing’s metallurgy. ACS Aero-Flow feeder housings are available in cast iron, and 304 or 316 stainless steel; in either 17-1/2 inch or 21-1/8 inch heights. The Aero-Flow Series feeders provide optimal service in applications with pressure differentials up to 15 PSIG, and elevated temperatures to 500ºF. 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.
