Sweep auger

Sweep augers

The name of the conveyors comes from their purpose – namely to move the products to the silo. Another popular name by which they are known is unloading augers. Sweeping augers are mounted on the bottom of flat silos. Usually up to about 90% of the silo capacity is emptied by gravity separation. Then the sweeping auger becomes irreplaceable. It rotates 360 degrees around the base of the silo and assists in the process of emptying the remaining silo products.
