The air atomization spray has small angle and will not collide with the wall.
Drying to achieve 1-8 micron small particle size powder;
The normal normal distribution of particle size is steeper and the particle size is more uniform.
Adjustable particle size
Material application scope is wider
The whole atomizing mechanism has no plastic gaskets, no motors, long service life and easy maintenance.
It can be upgraded to a coating atomizing mechanism for precise steel, and can use various metal materials.
The atomizing mechanism is easy to disassemble, assemble and clean, and easy to maintain.
2．Equipment superiority
An innovative airflow atomization structure is adopted in the atomization system. The airflow atomization structure adopts two-hole deviation mechanism to realize two-stage atomization. The uniformity of droplets is good. The particle size can be adjusted according to the two-dimensional curve of QFN-CX-NZY8-075VER2018-1A atomization system.
The spray nozzle of the atomization system is coated with diamond, which is more wear-resistant than the ordinary SUS304 material. The service life of SUS304 is 10 times higher than that of SUS304.
It can be upgraded to low temperature spray dryer (with Jo Maple's low temperature drying system QFN-CX-5-MD10), and spray drying is achieved at a minimum of 35 degrees Celsius. It is of great significance for the research and development of new materials. It can achieve spray drying of materials in a large interval of 35-280 degrees Celsius. The spray drying machine with high and low temperature can be realized. It is different from the high temperature spray dryer with a general temperature of 180-280 degrees Celsius.

QFN-CX-NZY8VER2018-075A atomization system:
For example, if the final average dry powder size is about 3 microns, the known condition is that the solid content of the feed solution is 10%.
Then the average wet droplet size required is 3/0.1=30 micron. The liquid intake is about 8 L/hr, the compressed air needs 0.2 MPA, and the intersection point is about 30 micron.
For droplets of other sizes, first determine the treatment capacity, make a vertical axis, find the approximate size of the droplets, and then find the intersection point to find the compressed air pressure.
Note: According to the influence parameters of density and viscosity of materials on droplets, the final average diameter of droplets should be 30 [-27,33]
The number inside represents the average SAUTER particle size (micron) measured by Toplephine.
