This creation is a kind of mill structure improvement,It is making medicinal material pulverizer more preferably practical effect； Main system: motor shaft in addition to being equipped with tool arm blade,An auxiliary knife edge is set again above what blade,The feeding inlet of cover corresponds to above what auxiliary knife edge,Therefore,When being intended in the material crushed input cylinder,Preliminary chopping is first done by auxiliary knife edge,Thinner crushing is done by the tool arm blade of lower section again,Reach can accelerate crush,And reduce tool arm blade by the impact force of material； Also,The periphery of cover is set as inclined-plane,It forms inclined-plane lid and closes what cylinder,Reach sealing property more preferably.本創作係一種粉碎機結構改良，乃使藥材粉碎機更佳實用功效；主要係：馬達轉軸除了設有刀臂刀刃，於刀刃上方再設一輔助刀刃，筒蓋之入料口對應於輔助刀刃上方，因此，欲粉碎之物料輸入筒體中時，先由輔助刀刃做初步切碎，再由下方之刀臂刀刃做更細之粉碎，達到可加速粉碎、及減小刀臂刀刃被物料之衝擊力；又，筒蓋之周緣設成斜面，形成斜面蓋合於筒體，達到更佳之密合效果。
