Abstract

The invention discloses a vertical mechanical pulverizer with a gas flow grading system, and belongs to a solid material pulverizing device. The pulverizer comprises a feeder, a pulverizing chamber and a grading chamber, an outlet of the feeder is connected with the pulverizing chamber, a pulverizing rotating shaft is arranged at the bottom of the pulverizing chamber, a rotating fixed cutter is connected with the pulverizing rotating shaft through a support, and a fixed pulverizing gear ring is arranged on the peripheral side of the inner wall of the portion, provided with the rotating fixed cutter, of the pulverizing chamber. The upper portion of the pulverizing chamber communicates with the grading chamber through a grading flow guide plate. According to the technical scheme, by means of the vertical mechanical pulverizer with the grading system, traditional Chinese medicinal materials can be directly pulverized into powder with the particle size being 250 meshes or above, and the powder is prevented from being blocked in the pulverizing chamber.

Description

technical field [0001] The invention relates to a solid material pulverizing device, in particular to a vertical mechanical pulverizer with an airflow classification system. Background technique [0002] In the process of modernization of traditional Chinese medicine, "micronization" is an important technical means in the production process of traditional Chinese medicine preparations. [0003] At present, most manufacturers adopt the traditional pulverization-sieve grading pulverization method for the "micronization" of traditional Chinese medicine, and the product is pulverized to more than 200 mesh, especially for viscous materials, it is very difficult to sieve the powder in the pulverizer. Due to the barrier of the sieve, crushing often produces "over-crushing". Pulverization is an exothermic reaction, and excessive pulverization will inevitably produce "overheating". If the crushing temperature is too high, according to the principle of capacity conservation, the cru...
