The invention discloses a low-heat-sensitive medical material disc-type jet mill. The low-heat-sensitive medical material disc-type jet mill comprises a medicine disc and a crushing disc, supporting legs are correspondingly fixed to the periphery of the lower end of the medicine disc, the four supporting legs are arranged in total, a second air inlet pipe is installed in the middle of the lower end of the medicine disc in a communicating mode, a fixing ring is fixed to the periphery of the upper end of the medicine disc, a fixing ring is fixed to the periphery of the lower end of the crushingdisc, the fixing ring on the medicine disc is connected with the fixing ring on the crushing disc, moreover, the outer side annular arrays of the fixing rings are connected through bolts, furthermore,nuts are installed at the upper ends and the lower ends of the bolts in a threaded mode, moreover, the nuts are located on the two sides of the fixing rings, a movable cover is movably installed on one side of the upper end of the crushing disc through a rotating shaft, a fixing buckle is installed on one side, which is different from the side where the rotating shaft is located, of the movable cover, the middle of the upper end of the movable cover is provided a medicine outlet in a communicating mode, and a sealing ring is installed on the periphery of the lower end of the movable cover. According to the low-heat-sensitive medical material disc-type jet mill, an air inlet of the crushing disc is increased, so that crushing of the medicine is facilitated.
Description
technical field [0001] The invention relates to the technical field of disc-type jet mills, in particular to a disc-type jet mill pulverizer for low-heat sensitive medical materials. Background technique [0002] Disc jet mill, also known as spiral jet mill, is mainly composed of feeding system, air intake system, crushing-classification and discharging system. The crushing mechanism that the jet mill is mainly suitable for determines its wide application range and high fineness of the finished product. Typical materials include: superhard diamond, silicon carbide, metal powder, etc. High-purity requirements: ceramic pigments, medicine, Biochemical, etc., low temperature requirements: medicine, PVC. By changing the normal air in the gas source part to inert gases such as nitrogen and carbon dioxide, the machine can be used as an inert gas protection equipment, suitable for crushing and classifying processing of flammable, explosive, and oxidizable materials. [0003] Exist...
