Can the Circle Feeder be used with materials that tend to fluidize and flow freely?
Yes, the Circle Feeder can be used with materials that flood easily when aerated, but have lower mobility when degassed. The initial Circle Feeder charge must be made with the discharge gate valve closed and the material allowed to degas before it is discharged. Subsequent charges must be made with a heel of degassed material in the bottom of the hopper to “seal the discharge” and prevent flooding.
