The invention discloses a preparing method for hyaluronic acid or salt particles of the hyaluronic acid and an obtained product. The hyaluronic acid particle preparing method is a dry process granulation method, the hyaluronic acid or salt powder of the hyaluronic acid is subjected to rolling, pulverizing, fine granulating, screening and discharging through a dry process rolling and granulating method under the situation that a bonding agent is not used, and the hyaluronic acid or salt particles of the hyaluronic acid are obtained. The product has the characteristics of being high in stackingdensity, weak in hygroscopicity, good in mobility and stability and the like; and in the usage process, the advantages that dissolving is easy, adding is convenient, dust waste and pollution are reduced, long-term storage is achieved, and the transportation powdering ratio is low. According to the preparing method, operation is simple, little equipment is needed, a bonding agent and ingredients donot need to be added, influences on the structure and the property of the hyaluronic acid or the salt of the hyaluronic acid are avoided, and industrial production can be achieved.
