Dredge Cutter Head; Dredge Cutting Head;Cutter Suction Dredger

Detailed Product Description:

Cutter Head and Suction Dredger - A cutter head for a cutter suction dredger to be mounted rotatably about a cutter head center axis with respect to a suction device for sucking up material cut loose by the cutter head from the bottom of a body of water, which cutter head includes a base ring, a boss spaced from the base ring in the direction of the center axis, and a plurality of arms which extend from the base ring to the boss and are distributed at regular intervals in the peripheral direction, each arm has a series of teeth located on the radially outermost parts of the arm and directed outwards at an angle with respect to the peripheral direction, the direction of rotation of the cutter head being set such that the teeth perform a cutting movement, with non-return mechanisms, preventing movement of cut material from the center axis to the exterior.

Cutter Head is one of the key structures of a CSD,for it largely determines the production quantity and the dredging efficiency.

The basic cutter head skeleton includes a hub, a ring and several curved arms that link the hub and ring together. The adapters with teeth or replaceable cutting edges are fitted on the front side of the cutter arm. Optimised arm profile, spacing and size, and tooth location and orientation mean top production and minimal downtime figures.

With decades of professional experiences in manufacturing dredgers' parts,We have advanced technology including CAD/3D simulation in components designing process.Therefore,we provide a wide range of cutter heads to the clients requests and any other specially used cutter heads.

We have performed many comparison tests between the original and custom-made LANGE Cutter Heads. In all cases there was a significant reduction in cost per m³ dredged.
