The invention relates to a novel method for carrying out impurity removal and purification on Chinese herbal medicine. Any two or three of a vibratory screening method, a magnetic metal adsorption method and a winnowing impurity removal method are selected to be combined to carry out impurity removal and purification on Chinese herbal medicine. The novel method can well solve the problem of removing various species and types of impurities. Moreover, due to adoption of a vibratory conveying mode, Chinese herbal medicine can be uniformly spread in the vibratory conveying process, and thus, the novel method is beneficial for various subsequent Chinese herbal medicine machining processes to sufficiently take effects.
