In 2019, my country's airflow milling market, the demand for medical sectors is the largest, reaching 27%; next is the field of new materials and chemical industry, demand proportion is 11% and 10%; biological, non-metallic The needs of mine and equipment manufacturing are between 5% and 7%; the demand in new energy and food sector is between 4% -5%; other areas are all over 3%. Pharmaceutical, new materials, and chemical industry are an important downstream application market for gas flow grinding in my country.
The design of the laboratory jet classifier must follow the following four principles: First, the material is fully dispersed, and the grading can be divided into thick, medium and fine three products.
Second, the stability of the flow field and has a strong attachment to the wall, and there is no rotating member and the drive motor in the classified equipment.
Third, the powder is rapidly graded in the classified cavity of the laboratory jet class, preventing the dispersed powder from agglomeration.
Four, improve the leveling accuracy of ultrafine powder. In the graded domain, the material is accelerated in several nozzles, the spray air flow intersection, resulting in severe collision, friction, cutting, and ultrafine pulverization of the particles.
ALPA built-in ultrafine pulverized laboratory cleaner, superfine powder pulverizer, particle size detection, powder characteristic detection related instruments, can accurately analyze different raw materials Property, providing 5G-50KG batch raw materials processing, rich microfourd experience and professional crushing equipment can significantly shorten the demand-developing cycle, solve the various problems encountered in the raw micronization process, welcome friends in need to call us !
