Abstract

The invention relates to a device for producing hot-briquetted metallic sponge, especially hot-briquetted sponge iron, from hot metallic sponge fines. Said device comprises at least one briquetting press (4), a means (6) for removing the fines from the briquettes produced by the briquette press (4), said means being mounted downstream of the briquette press (4). The device further comprises a means for returning the removed fines to the briquette press (4). The returning means is configured as a pneumatic conveyor means (20, 21), thereby reducing the costs for investment, service and maintenance and rendering the device more compact and space-saving.
