PURATEK discharge bottoms are suitable for discharging large sludge bunkers.
The discharge bottom consists of screw shafts arranged in parallel rows. This allows a large material bunker bottom area to be regularly discharged and prevents the material from building up. PURATEK large bunker discharge bottoms have proved themselves in discharging non-compacted materials and pasty sludges, such as sewage sludge. The screw shafts are drive-coupled via spur gears. The material is discharged throughout the complete width of the bottom.
After that, the discharged material is transferred into a rectangularly arranged conveyor system. The feed bunker can be made of sheet steel with stiffening profiles. Alternatively, a concrete bunker can be provided locally by the customer.
