By working with Spiroflow, this customer successfully employed three new flexible screw conveyors to convey flour from outside silos into their process inside, vastly improving the performance and cleanliness of their system.

– A combination of flexible screw conveyors were recommended by Spiroflow’s local manufacturer’s representative as a dust-free and efficient alternative.
– In this application two outdoor silos were provided with rotary valves on the discharge.
– The flexible screw conveyor inlets were designed to match the existing valve’s flange pattern for ease of installation.
– Two Spiroflow Model FSC-658 conveyors with flat profile screws, convey flour at a combined rated of 24,000 lb/hr/ 10,900kg/hr into a common ribbon blender inside the building about 18’/ 5.5m from the silos.
– After the batch is mixed a Spiroflow model FSC-834 conveys the product directly from the blender at the same rate 20’/ 6m at a 60° angle into the downstream process.
