[0002] In the field of precious metal processing and recycling, traditional powder production technology is mainly based on mechanical methods such as ball milling. These methods grind larger metal blocks into powder through physical impact and abrasion. Although these technologies are simple and have a long history, they have multiple shortcomings, especially in terms of efficiency, energy consumption, environmental impact and product quality control: 1. Inefficiency and slow speed, mechanical grinding usually requires a long time to run to achieve the desired particle size, which leads to low production efficiency; 2. Difficult particle size control, mechanical grinding is difficult to accurately control the particle size distribution of the final powder, which may lead to unstable product quality; 3. High energy consumption, especially when processing hard metals; 4. Poor environment, the dust and noise generated by mechanical methods pose a threat to the environment and the health of workers.
[0003] Water atomization technology provides an alternative method to atomize molten metal into powder by high-pressure water. Although this method has advantages in particle size uniformity and oxygen content control, it still has some practical operation problems, such as equipment clogging and management of metal solidification rate, which limits its application in specific metals or alloys. To this end, we propose a new atomization powder spraying device to solve these problems. Utility Model Content
