Systems and methods for pulsed direct current magnetic actuated milling of pigment dispersions

摘要

A system for pigment milling includes a pulsing direct current (DC) source that generates a DC pulse, an electromagnetic field generating subunit that includes an electromagnetic coil coupled to the pulsing DC source to receive the DC pulse and to generate a magnetic field, and a rotating container subunit that includes a container for holding magnetic particles and ink pigment particles in an ink carrier, and a rotating subunit to rotate the container. A portion of the container is disposed within the electromagnetic coil and generation of the magnetic field causing motion of the magnetic particles thereby dispersing the ink pigment particles within the ink carrier.
