Separate drives for the agitator and metering auger allow appropriate agitation at all auger speeds. Metering augers are available at full pitch or 1/2 pitch configurations with helix diameters from 1/4in to 2-1/4in. The PF Series can be configured with controls for intermittent agitator operation, which is particularly useful when operating at very low rates. Additionally, this variable speed agitator permits thorough mixing in all areas of the metering section.
