Preparation method of traditional Chinese medicine calculus-removing granules

The invention discloses a preparation method of traditional Chinese medicine calculus-removing granules, and relates to the technical field of preparation of traditional Chinese medicine preparations. The preparation method comprises the step of adopting a granulating device for preparation; putting auxiliary material powder in a material pot for preheating, and introducing air via an air inlet pipeline, wherein the air inlet amount is controlled to be 300-500 g/m and the air inlet temperature is controlled to be 55-65 DEG C; spraying all the calculus-removing particle extract into a material pot, mixing the calculus-removing particle extract with the auxiliary material powder, and conducting granulating, wherein the air inlet rate is controlled to be 700-900 g/m and the air inlet temperature is controlled to be 60-70 DEG C; and after the calculus-removing particle extract is fed, conducting drying until the moisture of the particles is lower than 3%, wherein the air inlet amount is controlled to be 500-700 g
