Shenyang Vacuum Atomization Powder-Making Equipment Manufacturer Introduces the Complete Process of Atomizing and Grinding Powder for Powder Metallurgy Equipment

【Summary Description】Introducing the Shenyang Vacuum Atomization Powder-Making Equipment Manufacturer: A Comprehensive Overview of the Entire Atomization and Grinding Process for Powder Metallurgy Equipment When performing atomization, there’s an inherent relationship between the energy absorbed by the liquid during the process and the resulting particle size of the atomized droplets—specifically: the greater the energy absorbed, the smaller the particle size; and vice versa.
Shenyang Vacuum Atomization Powder Manufacturing Equipment Manufacturer Introducing the complete process of atomizing and milling powder metallurgy equipment.
Process 1: When larger liquid droplets are subjected to an impact force, they instantly shatter into numerous smaller droplets. Assuming the liquid temperature remains unchanged during this fragmentation process, the energy change in the liquid can be analogously compared to an increase in its surface tension. During atomization, there’s a direct relationship between the energy absorbed by the liquid and the resulting droplet size: the greater the energy absorbed, the finer the droplets; conversely, lower energy absorption leads to larger droplets.
Process Step 2: As liquid particulates break apart, they often come into contact with each other, coalescing once again into a larger liquid particle. Simultaneously, the shape of the liquid particles begins to transition toward a spherical form. During this process, the total surface area of the system decreases—making it a spontaneous process.
Phase 3 of the entire process: Liquid particulates are cooled to produce smaller solid particles.
Characteristics of metal material-based atomization powder-making equipment:
This machinery boasts high grinding capacity, effortless operation, no damaged components, produces finely ground particles that are uniform in size, and is easy to assemble.
Metal powder has always been a critical raw material in industrial production. Traditional methods for manufacturing metal powders, such as high-energy milling, have already been scaled up for industrial use. However, due to the inherent complexities of these processing techniques, they often suffer from drawbacks like relatively large particle sizes, uneven particle distribution, low throughput, and significant wear on machinery—frequently requiring costly equipment replacements—and even struggle to meet precise manufacturing requirements in terms of particle morphology. The advent of ultrasonic metal powder milling has now broken this longstanding bottleneck, opening up new possibilities for more efficient and reliable production.
The basic principle behind using ultrasonic metal materials for atomizing and grinding involves an ultrasonic transducer (ultrasonic power supply) that converts ordinary alternating current into high-frequency electromagnetic oscillations. These oscillations are then transformed into high-frequency vibrational energy via a sensor, which is further amplified by an amplitude-modulating horn before being transmitted to the specialized tool head. When molten metal comes into contact with the tool head, ultrasonic vibrations cause it to coalesce into a thin boundary layer. As the tool head’s working surface reaches a specific amplitude, this delicate liquid layer is shattered and ejected from the material’s surface, creating the atomized powder.
The software system for the metal material atomization powder-making equipment consists of a 35 kHz ultrasonic vertical vibration sensor, a disc-shaped specialized tool head, and matching dedicated LED drivers. After the sensor generates ultrasonic waves, they are transmitted directly to the disc-shaped tool head, where they are converted into axial ultrasonic vibrations. Once customers receive the equipment, they should first securely fix it in place—using only the provided mounting plate—and then activate a specific type of motor to initiate system rotation. Before starting operation, the tool head must undergo appropriate preheating (with ambient temperature ideally close to that of the metal solution). Finally, simply turn on the ultrasonic LED driver, and the metal solution will be sprayed onto the top of the tool head, causing it to atomize into fine powder.
