Abstract

A table-type airflow crushing device for laboratories relates to the technical field of powder material crushing. A main body of the table-type airflow crushing device comprises an air compressor, an air storage tank, a precise filter, an air freezing dryer, a degerming filter, a fluidized bed airflow crusher, a cyclone separator, a deduster and a draught fan which are sequentially connected in closed mode through pipelines, and the fluidized bed airflow crusher, the cyclone separator and the deduster are fixed on the same worktable. The table-type airflow crushing device for laboratories is reasonable in structural design, has the advantages of being low in noise and free of vibration, is widely applied to ultrafine crushing of dry powder materials of medicines, chemical engineering, metallurgy and the like to prepare samples in the laboratories, can obtain products with uniform particles and small particle size distribution range, is good in sealing performance and free of dust, and does not cause unnecessary sample loss.

Description

Technical field: [0001] The invention relates to the technical field of pulverizing powder materials, in particular to a bench-top airflow pulverizing equipment used in a laboratory. Background technique: [0002] Jet milling equipment is widely used in chemical industry, minerals, metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health products, new materials and other industries. The crushing mechanism determines its wide application range and high fineness of finished products, which can meet High-purity requirements, such as: ceramic pigments, medicine, biochemistry, etc.; can meet the requirements of low temperature, such as: medicine, PVC. By changing the ordinary air in the gas source part to inert gases such as nitrogen and carbon dioxide, it can be transformed into inert gas protection equipment, which is suitable for crushing and classifying processing of flammable, explosive, and oxidizable materials. Jet milling equipment usuall...
