This invention discloses a traditional Chinese medicine grinding device, comprising a grinding cylinder and a drive box. The grinding cylinder has a cover plate on its upper part. Inside the grinding cylinder, from top to bottom, are a primary grinding mechanism and a secondary grinding mechanism. The primary grinding mechanism includes a primary mortar and a primary grinding pestle, and the secondary grinding mechanism includes a secondary mortar and a secondary grinding pestle. Both the primary and secondary mortars have leakage holes, with the diameter of the leakage hole in the primary mortar being larger than that in the secondary mortar. The drive box is located at the bottom of the grinding cylinder, and a drive mechanism is located inside the drive box. The drive mechanism includes a motor frame, on which a drive motor is mounted. A rotating shaft is connected to the output shaft of the drive motor. The primary mortar, primary grinding pestle, secondary mortar, and secondary grinding pestle are all mounted on the rotating shaft. This invention employs a multi-stage grinding design, achieving uniform and efficient grinding of traditional Chinese medicine through progressively finer grinding, thus improving grinding efficiency.
