Study on Grinding Technology for Seafloor Mineral
To apply a ball mill to the grinding unit for seafloor mineral processing grinding experiments were carried out using a small-scale ball mill applicable to high-pressure condition. In the experiments wet grinding and water-filled grinding of size-classified silica sands were carried out at three rotation rates to compare the grinding

Advances in Comminution comes at a critical time. It focuses on the dilemma of needing to grind materials to ever-finer sizes while maintaining reasonable energy costs. The selection and sizing of stirred mills for regrinding and ultrafine grinding applications do not lend themselves to conventional methodologies therefore new approaches are being developed.
