Rotary feeder improves conveying efficiency
The ACS Valves Aero-Flow series of rotary feeders is designed to convey pharmaceutical ingredients efficiently. Air enters the feeder through its two endplates. As the air circulates around the endplates, the air pressure increases and prevents the ingredients from getting into the feeder’s seals and bearings.
Air passes through a slot in the bottom of each endplate into the feeder housing and mixes with material being conveyed by the 10-vane rotor. The feeder thus aerates the material and helps it to flow freely. The aeration also helps to keep sticky or abrasive ingredients away from the feeder housing, endplates, and rotor, thus reducing wear on the unit.
In addition, the rotor design prevents material from building up inside the feeder. The precision tolerance of the 10-vane rotor design inside the unit prevents excess air from passing through the valve.
