Design Aspects for Cutter Heads Related to the Mixture Forming Process When Cutting Coarse Materials
Spillage, defined as the soil that is cut during the dredging process but not sucked up by the suction pipe, reduces the productivity of the cutter suction dredger and therefore needs to be minimised.
Computer simulations are becoming a significant, controllable and safe way of getting theoretical knowledge out of the “labs” and onto the dredge sites.
Laboratory experiments demonstrate from a wear point of view the inefficiency of cutting tools on a cutter suction dredger. Recommendations are made to optimise the cutterhead design and cutting process.
