The Auger Filler work principle

The auger drive rotates the auger at a constant speed to feed product out of the funnel. The agitation blade, separately driven and controlled, rotates in the opposite direction to the auger, homogenising the powder, and breaking any product bridge which can form in non-free flowing powders. The agitation blade extends down to the throat of the funnel preventing rat-holing and cavitation and ensures that the auger flights are consistently filled.

The lower parallel flights of the auger that sit within the funnel are precision machined so that each pitch has a precise volume If an auger with flights of perfectly even pitch, evenly filled with powder of constant bulk density and even particle distribution, rotates a precise number of revolutions, theoretically there would be zero deviation in dose from one cycle to another. In most applications where these conditions more-or-less apply, volumetric filling is entirely appropriate and typically, accuracies in the range of ± 0.5% to 2% can be expected.

Where such factors as variations in bulk density and particle size/distribution, high cost, or criticality of dose demand closer tolerances, weigh-filling technology can be employed.
