Description

Technical Field

[0001] The utility model relates to the technical field of copper-tin alloy powder processing, and more specifically to a production device for copper-tin alloy powder. Background Art

[0002] The methods for making copper-tin alloy powder generally include mechanical alloying, chemical reduction and laser cladding. The mechanical alloying method is to mix the two metal materials, copper and tin, in a ball mill, and use mechanical energy to change the arrangement of atoms to form new compounds, thereby producing copper-tin alloy powder.

[0003] In the process of making copper-tin alloy powder by ball mill, the metal materials are ball-milled and mixed by the medium inside the ball mill. During the processing, large particles of metal materials may be thrown out directly from the discharge port if the processing is not thorough. In addition, the powder is usually collected manually after the medium is separated from the inside of the ball mill, which is not conducive to improving the production efficiency of copper-tin alloy powder. In view of this, we propose a production device for copper-tin alloy powder. Utility Model Content
