Lithium battery recovery powder reduction equipment and ternary lithium battery recovery powder reduction method

The invention belongs to the technical field of lithium battery recovery, and particularly discloses lithium battery recovery powder reduction equipment capable of basically avoiding caking and highly toxic substances in the reduction process, and a ternary lithium battery recovery powder reduction method for reducing ternary lithium battery recovery powder by adopting the lithium battery recovery powder reduction equipment. According to the lithium battery recovery powder reduction equipment, a spiral material scattering device is arranged in a furnace tube of a reduction rotary furnace, so that materials can be prevented from caking in the furnace, and the effect of controlling the retention time of the materials in the furnace is achieved; the reduced materials can be quickly transferred into a discharging screw from a high-temperature area through a spiral material scattering device and a spiral discharging sealer, so that the temperature of the reduced materials in the furnace is effectively prevented fr
