Overview
Unlike volumetric feeders where a single auger is typically located
at the very bottom of a converging “V” shaped trough — across
which many products easily and often bridge, regardless of whether
or not the trough is vibrated or agitated — Acrison’s various model
Double Concentric Auger Dry Solids Volumetric Feeders not only
Discharge Conditioning/Feed assure both positive flow and feed, but also, always maintain total
Cylinder Chamber control of the product for unsurpassed levels of performance.
Metering Especially effective when metering the many different varieties of
Auger amorphous products, the unique “Inter-Auger-Action” produced by
rotation of the Double Concentric Augers operating at dissimilar
speeds, “conditions” the product to a remarkably consistent and
uniform state while circumferentially filling the metering auger
precisely, efficiently and reliably.
“Inter-Auger-Action” — acknowledged as the most viable and

this model features a ten inch diameter
Intromitter or “conditioning” auger. The outer (larger) auger, identified as the Intromitter, rotates in the
same direction as the (smaller) metering auger, but at a much slow-
er speed. The two augers are mechanically geared together in a
common precision drive network, powered by a single variable
speed gearmotor.
Metering accuracies generally range between ± 1 to 2 percent
or better (error) for the majority of products based on a given
number of consecutive one minute samples.
