  • Inline metal detection fitted to system feeds
    Buffer hoppers and dosing valves for control of product moving from the main silos
  • 2 x Weigh platforms for bag weighing and check weighing
  • Vibration table for maximum compaction of product
  • Inline ticket printing system accessible to the operator for application of tickets
  • Bag data transmission and logging
