... tests of a manganese nodule crusher of a pilot mining robot, MineRo-II, are carried out to investigate nodule breaking ability of the crusher. Manganese nodules should be crushed into smaller pieces in order to assure the slurry flow of lifting system. In this study, artificial nodules are used instead...

... AND PROCEDURES To simulate the actual differential pressure in the bends of the flexible hoses, it was essential to develop the artificial nodules similar to that of the polymetallic nodules in density and hardness to be mixed with water to form slurry. Fig 5 and 6 shows the polymetallic nodules and Artifical...

... and nodules. It is simple in structure, reliable in working only with one power, high pick up rate, and low sediment content. This pickup device was tested in the laboratory with imitation sediments of 3 kPa in shear strength and artificial nodules of sizes between 15 and 75 mm in diameter. Furthermore...
