  • Solid-bowl centrifuge screw having a screw flight
    Patent number: 11406991
    Abstract: A solid-bowl centrifuge screw with a screw flight is provided. The screw flight has at least a first welding layer on a base body of the solid-bowl centrifuge and at least a second welding layer on the first welding layer. Thus, plural welding layers are disposed successively on one another and are applied by shaping build-up welding.
