Description

technical field [0001] The invention relates to the technical field of jet milling materials, in particular to a jet milling unit. Background technique [0002] The pulverizer is needed in the ultra-fine pulverization process. The pulverization effect of the mechanical impact pulverizer, vibration mill and stirring mill in the existing pulverization methods is not satisfactory, and a large amount of heat will be generated when the material is pulverized during use. The deterioration of heat-sensitive materials will lead to the aging of equipment, and the wear and tear of equipment will also pollute products. Therefore, these mechanical pulverizers can no longer fully meet people's increasingly high requirements for ultra-fine powder materials. Some manufacturers use jet pulverizers instead of mechanical pulverizers. Impact mills, vibration mills and stirring mills, but the existing jet mills have complex structures, high equipment manufacturing costs, high energy consumption...

Problems solved by technology

[0002] The pulverizer is needed in the ultra-fine pulverization process. The pulverization effect of the mechanical impact pulverizer, vibration mill and stirring mill in the existing pulverization methods is not satisfactory, and a large amount of heat will be generated when the material is pulverized during use. The deterioration of heat-sensitive materials will lead to the aging of equipment, and the wear and tear of equipment will also pollute products. Therefore, these mechanical pulverizers can no longer fully meet people's increasingly high requirements for ultra-fine powder materials. Some manufacturers use jet pulverizers instead of mechanical pulverizers. Impact mills, vibration mills and stirring mills, but the existing jet mills have complex structures, high equipment manufacturing costs, high energy consumption, and high processing costs; single machine processing capacity is poor (the output is less than 2t / h), Not suitable for large-scale production; the particle size of the product is difficult to reach the submicron level, and the output drops sharply when the particle size is below 10um, and the processing cost increases sharply
