Airflow pulverization technology is applied to high-grade pressure powder makeup manufacturing, improving the powder structure, has great improvement of powder performance and product quality. Airflow pulverization technology has broad application prospects in the cosmetics industry.
Ultrasonic airflow pulverizer principle and characteristics:
When the compressed gas passes through the injector, the pulverized raw material enters the pulverizer, there are multiple pulverized nozzles per circumscribed in the pulverizing chamber, and the supersonic air flow is sprayed. High speed shock of airflow, and the material collide with each other, the grading tube separates the thicker particles, the crude particles circulate return to the pulverizing chamber to continue to be pulverized, after the internal closed circuit circulation is pulverized, and finally the distribution of uniform dispensing in the discharge port. .
1, suitable for dry ultrafoil. Due to the large impact speed, it can reach 2.5 mep, generally easily obtain 1-10 microns (um) particles, depending on the material properties, it is possible to obtain less than 1 micron (um) particles.2, due to the interior of the pulverizer, the coarse particles in the article continue to circulate, and thus the particles can be uniform and the particle size distribution range is obtained.
3, the equipment has the advantages of short smashing time, simple structure, convenient operation, small area, low noise (72 decibel), and vibration.
4, the efficiency of the pulverization can be continuously pulverized, and the purity of the pulverized product can be maintained.
5. Introducing the latest technology in Germany, after years of technical experience accumulation, equipment comprehensive performance has been equal model model;
6, suitable for various powders of Mogli hardness 10 below the various powders Poly, spheroidal shaping, etc .;
7, the material fineness can be adjusted between 3 to 150 μm, and some material D50 value can reach 1.5 μm;
8, due to its special case-free, spray, It is especially suitable for ultrafine pulverization of high purity materials;
9, no heat generation during pulverization, excellent thermal material is crushing;
10, wear-resistant protection: internal and graded wheels can choose from various wear resistance Protective materials such as alumina, zirconia, organic materials;
11, environmental protection and automation design, systematic closed operation without dust leakage, can be used with touch screen and PLC automatic monitoring equipment;
12, multi-purpose design: can be used in series with airflow classifiers, universal crushers, better meet the particle size requirements of powder;
13, application areas: chemical, minerals, Chinese medicine, Makeup, food, flame retardant, printing, activated carbon, resin, etc .;
Survantile airflow pulverizer to material impact shear effects and materials and other components, friction, cutting materials . Therefore, the average particle size of the material after the gas flow is thin, the particle size distribution is narrow, the particle surface is smooth, the particle shape is standardized, the purity is high, the activity is high, and the dispersibility is good; the low melting point and thermal material and biologically active article (because the gas flow is pulverized The machine is powered by compressed air, and the adiabatic expansion of the compressed gas at the nozzle reduces the system temperature). According to statistics, the internationally 15% airflow pulverizer is used for ultrafine preparation. Supersonic pulverizer has been improved in the past, and its structure is constantly improving, and the comminuted performance is constantly increasing. In order to meet the development of information technology, biotechnology and new material technology, the higher requirements of particle size, purity and particle size distribution of powder products, the development of ultrafine gas flow should pay attention to the following aspects: in existing foundation Upper, improved, optimize ultrafine gas flow, develop new equipment, and pay attention to the matching design of smash and grading system.
The new era creates new demand. As economic growth is gradually changed from the intensive environmental protection, each industry is facing unlimited opportunities and challenges. Among them, the ALPA powder technology, which is a typical representative of industrial powder equipment manufacturing enterprises, with the new era - environmentally friendly powder equipment, to promote transformation and upgrading of all walks of life, highlighting their own business while achieving green development of partners value.
