Sintering devices, sintering assemblies, and associated methods

A sintering assembly comprising:

• a sintering device comprising:
• at least two rollers comprising an electrically conductive outer ring;
• and
• at least two brushes contacting the at least two rollers, the at least two brushes configured to pass an electric current through each electrically conductive outer ring;
• and
• an enclosure operatively connected to the sintering device, the at least two rollers of the sintering device configured to receive a feedstock from an inlet of the enclosure and configured to produce a sintered product to an outlet of the enclosure.

A method of sintering a feedstock, comprising:

• introducing a feedstock to a sintering device, the sintering device comprising:
• at least two rollers spaced apart and defining a sintering space therebetween, each roller comprising an electrically conductive outer ring;
• and
• at least two brushes disposed on each of the at least two rollers and configured to pass an electric current through the electrically conductive outer ring of each of the at least two rollers;
• continuously passing the feedstock into the sintering space between the at least two rollers of the sintering device, the at least two rollers positioned to contact the feedstock;
• applying an electric current across the at least two rollers through the at least two brushes, the electric current resistively heating the at least two rollers;
• and
• transferring heat to the feedstock from the at least two rollers to produce a sintered product.
