Shaftless screw conveying
Dutch Spiral bunkers can be applied in many different sectors as a storage, transfer and discharge tank of dewatered screenings and sludge. The Bunkers are made according to the wishes and requirements of the costumer.
In order to prevent a bridge formation of sticky and coarse materials over the diameter of the trough multiple screws are installed on the bottom of the bunker.The shaftless screws cover a large part of the bottom surface which results in efficient interception and an easier discharge. Due to the distribution of the material over the multiple screws the individual screws can function more energy-efficient.
