-. Overview of metal powder making equipment:
- Particulate metal powder has always been an important raw material in industry. Traditional metal powder manufacturing methods such as high-energy crushing have entered large-scale industrial production. However, due to the process method, the process is more complex and There are disadvantages such as large particle size and uneven particle size. The powder production capacity is small, the equipment loss is large, and the distribution shape often needs to be replaced. It is also difficult to meet production requirements. The emergence of ultrasonic metal powdering breaks this deadlock.

The basic principle of ultrasonic metal atomization powdering is to use an ultrasonic generator (ultrasonic power supply) to convert ordinary alternating current into high-frequency electromagnetic oscillation and then convert it into high-frequency through a transducer The mechanical vibration is then amplified in amplitude and transmitted to the tool head through the horn. When the metal liquid contacts the tool head, it spreads into a liquid film under ultrasonic vibration. When the working surface of the tool head reaches a certain amplitude, the thin liquid layer is shattered and flies out from the working surface to form atomization.
Functions of the main components of metal powder making equipment:
. Ultrasonic vibration source (driving power supply): converts the mains power into high-power and high-frequency power supply to the transducer.
.Transducer: converts high-frequency electrical energy into mechanical vibration energy.
-.Water-cooled horn: connect the transducer and horn and cool it with water so that the high temperature of the tool head will not be transmitted to the transducer
.Water-cooled horn: connect and fix the transducer It amplifies the amplitude of the transducer and transmits it to the tool head.
.Tool head: Use ultrasonic energy to vibrate the metal liquid on the tool head and fly out of the tool head into mist.
.Connecting bolts: tightly connect the above components

Features of metal powder making equipment:
This equipment has a large powder production capacity, stable operation, no wear parts, and small powder particles. Easy to install evenly.
The metal powder making system consists of the ultrasonic longitudinal vibration transducer, the first section of the transducer, the second section of the water-cooled horn (which plays a cooling role to protect the temperature of the transducer from rising), and the third section of the horn (from which the installation begins) Functionally installed on the workpiece) Finally, the tool head is equipped with a special drive power supply to form a transducer to generate ultrasonic waves, which are then transmitted to the tool head and converted into radial ultrasonic vibrations. After the customer gets the equipment, he must first fix the equipment. Before starting work, the tool head must be properly preheated (the temperature should be close to the metal solution), and then turn on the ultrasonic drive power supply to spray the metal solution on the tool head to atomize it and produce powder.
