The Model BDF-1.5-2 high-performance volumetric feeder incorporates two independently driven metering augers with a dual agitator flow-inducing mechanism to provide versatile metering and hoppering capabilities over a wide feed range. Suitable for both continuous and batching applications, the feeder eliminates the task of changing the size of the metering auger whenever a wide feed range is required. Additionally, the unit provides both high (rapid feed) and low (dribble) feed outputs for batching applications. In a batching mode, a larger metering auger feeds the majority of the material for the selected batch weight and a smaller metering auger provides the final “dribble” amount so that the highest degree of batch cut-off accuracy can be achieved.
