The first pressure regulating valve and the second pressure regulating valve are connected to the airflow pulverizer. The third pressure regulating valve is connected to the feeder.

Description

Technical field [0001] The present invention relates to the field of materials technology jet milling, jet mill, to a particular group. Background technique [0002] Ultrafine grinding mill pulverization process requires these methods unsatisfactory effect pulverization, pulverization manners conventional mechanical impact mill, a vibration mill and agitator mill, and will generate a lot of heat when the material crushed during use so that heat-sensitive materials deteriorate, leading to wear and tear of aging equipment, the equipment will be contaminated products, these mechanical mill can not meet the people's growing material ultra-fine powder of high demand, some manufacturers use a jet mill to replace machinery impact mill, a vibration mill and the stirring mill, a jet mill but the complexity of the conventional structure, the high cost of equipment, energy consumption, processing costs are large; single poor processing capabilities (yield less than 2t / h), not suitable for...

AI Technical Summary

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
