The equipment is customized on the furnace equipment of the research assistant instrument, which is suitable for rotary sintering of powder materials, uniform rotation of materials, and good heating uniformity. The quartz furnace tube is placed in the middle of the furnace body, and the other end of the furnace tube is connected to the rotary sealing assembly with a clamp to facilitate the entry and exit of materials and the air pressure monitoring in the tube. During the rotation of the furnace tube, the powder can be evenly stirred without accumulation, and the material can also be completely automatically discharged in one direction during the discharging process, which is convenient to operate. It is widely used in battery cathode and anode materials, non-strong acid and alkaline powder materials, and granular materials. It can be fired under vacuum or under the protection of an atmosphere.
