Metal Powder Ultrasonic Sieving Machine

Introduction of Metal Powder Ultrasonic Sieving Machine

In the production of metal powder processing, the powder must be sieved after reduction and grinding. Because powder sieving can not only remove unground oversized particles or agglomerates, but also ensure uniform particle size of metal powder, powder metallurgy also relies on sieving after sintering and pressing to ensure product quality before entering the next production process.Metal powder ultrasonic sieving machine can accurately sieve metal powder as small as 20 microns, and can remove contaminants such as large particles and agglomerates from metal powder.

Application of Metal Powder Ultrasonic Sieving Machine

Metal powder ultrasonic sieving machine is mainly used for supporting metal 3D printers. After the printing is completed, the residual powder is recycled and utilized. Optional ultrasonic cleaning system and inert gas protection system. Equipped with an ultrasonic system to increase the screening rate, while avoiding the adsorption of fine powder and reducing the probability of clogging of the screen mesh. Fine metal powders or special alloy powders are more likely to oxidize when exposed to the air. They are really high-end metal powders in the metal 3D printing industry. They have higher requirements for oxygen-containing powders. They cannot be exposed to air when they are sieved. Therefore, this product can be equipped with an inert gas protection system during the screening process, and the oxygen content of the system can be directly controlled throughout the whole process to prevent the metal powder from contacting the air, ensuring the purity of the powder and improving the quality of metal 3D printing parts.

Benefits of Metal Powder Ultrasonic Sieving Machine

1. During the metal powder screening operation, the feeding method is manual interval feeding, and the labor intensity of the operator is relatively high. The screening quality is completely limited by the operator's operating level, and there are unstable factors. In addition, the powder loss is large, polluting the environment, and the entire operation is carried out in the air. When the operator uses the shovel to feed, the powder will be splashed and accompanied by the dust flying under the influence of the vibration of the sieve machine, which will directly cause the metal yield to drop and make the The dust content in the air exceeds the standard, pollutes the working environment on site, and causes people to inhale dust to cause disease. Metal powder sieving machine is a device and method for sieving ultrafine metal powder under the protection of nitrogen or inert gas to reduce pollution Sensitive powders are isolated from ambient air and moisture, reducing powder cross-contamination and eliminating operators having to touch powders, ensuring a safer environment.

2. Sieving metal powders is challenging because fine particles tend to clog the screen, reducing flow rates and resulting in loss of quality product. Metal powder ultrasonic sieving machines use ultrasonic frequencies applied to the sieve, preventing clogging of the sieve holes. This allows metal powders to be screened reliably and consistently, while the screening equipment remains in optimal operating condition. Metal powders down to 20 microns can be precisely sieved.

3. Ultrasonic sieving can make the powder pass through the sieve faster, thereby increasing the sieving capacity by ten times.

4. Prevents clogging and reduces the time spent cleaning the mesh, a simple retrofit solution for all new and existing vibrating screens and screening machines
