▎ 摘　　要

NOVELTY - The mixer has a connecting plate fixedly sleeved on a rotating shaft. An outer wall of the connecting plate is fixedly connected with multiple device plates (83). A position of an inner wall of a machine body corresponding to the device plate is provided with an annular groove. A gear ring, a device plate and a circulating assembly (84) are fixedly installed in the annular slot. The circulating assembly is installed on the device board. The rotating shaft and the spiral mixing blade are provided with a circulation mechanism (8). USE - Internal circulation graphene powder mixer for use in biological medicine and drug delivery applications. Uses include but are not limited to optical, electrical, mechanical characteristics, material learning, micro-nano processing, energy and biological medicine. ADVANTAGE - The internal circulation graphene powder mixer improves the production efficiency, can realize the working mode change of the device mixing and discharging, has mixing function and discharge function, reinforcing mechanism practicability, reduces the raw material accumulation, and improves the production efficiency.
