Sweep Augers are used for emptying Flat Bottom Silos of stored grain after discharge by gravity has stopped. The Sweep Auger is pivoted in the centre discharge hopper of the Silo. It digs into the grain pile and pulls it towards the centre discharge hopper. On completion of one rotation of the Silo floor all the stored grain is discharged. The Sweep Augers are manufactured to strict quality standards and are driven by flameproof motors and oil bath speed reduction O
