[0002] The high-speed mixing granulator is supported by the machine body, with the pot as the material container, and the stirring rotation and cutting knife transmission as the power. The material is stirred by a stirring paddle, so that the material is rolled and mixed evenly in a short time, and then made into granules by the cutting knife, and finally discharged from the discharge port. By changing the rotation speed of the stirring and cutting knife, the granules of different sizes can be obtained, which plays a great role in the drug production process.
