Apparatus for grinding chinese herb medicines into super-fine powder using chillness

Abstract

The invention discloses a cryogenic traditional Chinese medicine ultrafine pulverization device, which is used for pulverizing materials. It is composed of a refrigeration exchange system, a coarse pulverization system and a low-temperature air flow pulverization system; 1. Two gas compressors, refrigerators, and heat exchangers; the coarse crushing system mainly includes sealed feeders, the first and second spiral precoolers, coarse grinders, the third cyclone separator, and the third dust collector; The low-temperature airflow pulverization system mainly includes a compressor, a fluidized bed airflow pulverizer, the first and second cyclone separators, the first and second dust collectors; the raw materials are subjected to low-temperature treatment during coarse pulverization, and the gas and solid are subjected to gas treatment after coarse pulverization. Solid separation pre-cools the coarsely crushed material again, and then enters the fluidized bed jet mill for fine grinding, so that the material is more refined. Therefore, the present invention has high crushing capacity, fine particles of the crushed material, and high powder quality. At the same time, the cold air is recycled and reused in the fully enclosed system, which saves energy and further reduces costs.

Description

technical field [0001] The invention relates to a jet mill. Background technique [0002] At present, most of the powder classifiers are crushed at normal temperature, so some materials cannot even be crushed, some materials are crushed at normal temperature, and the output is low, and some materials are easily oxidized at normal temperature, and the cost will be reduced if liquid nitrogen is used for refrigeration. Higher (for crushing at full or half-open state). Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a cryogenic traditional Chinese medicine ultrafine pulverization device, which can pulverize some materials that are easily oxidized at room temperature, and has high output and low cost. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: [0005] This cryogenic traditional Chinese medicine ultrafine pulverization device includes a refriger...
