To improve flow consistency, the supplier used a feed bin attached with a Spiralator, a vertical lifting agitator that gen- tly and continuously lifts the mate- rial closest to the bin's wall to aid in material flow. Testing showed this setup could provide reliable flow of the fragile base material with negli- gible material damage. "For the raw feed bin, we're able to feed material without oper- ator intervention. Additionally, we improved breakage of the raw consistent volumetric feed of both materials with little variability and that it's easy to empty and clean between batches thanks to its sim- ple disassembly. The supplier also suggested an additional smaller feed screw to help handle the required feedrate range. To prevent the material from bridging in the bin feeder, the sup- plier tested the material in two different bins with different out- let diameters and no bin agitation. Both of these options experienced The supplier's newly renovated test center has a wide range of conveying and feeding equipment that can be arranged to mimic the customer's application.
