The system includes a heating device, a deposition device, a coating device, and a support configured to support the bulk material. The heating device heats the metal material to form particles having a softened or molten state and the coating device coats the metal material with the insulating material from the source and the deposition device deposits particles of the metal material in the softened or molten state on the support to form the bulk material having insulated boundaries.

The invention relates to non-ferrous metallurgy and the electrolytic production of aluminium, and can be used for lining the cathode assembly of an electrolytic cell. The present method consists in laying materials while simultaneously distributing same over the surface of a base and levelling them at a height measured from the plane of the top edge of the shell of the cathode assembly of the electrolytic cell by gradually moving a device for installing unformed lining materials along the longitudinal axis of the cathode of the aluminium electrolytic cell. Said device is configured in the form of a bridge equipped with a mechanical drive for movement. The bridge has guides on which a frame is mounted for vertical movement, said frame having cassettes provided with gates with a mechanical drive. The technical result is reduced labour costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.
