Copper powder is a very dense and typically spherical metal powder that is used in the electronics industry due to its conductive properties. Screening copper powder is a process that requires close monitoring of both the mesh openings and the level inside of the machine. The sphericity of the powder can sometimes lead to blinding of the screen mesh as perfectly round particles can plug inside the square mesh hole at 4 points. If the material is allowed to sit on the screen and afforded the opportunity to settle in the hole, it most likely will. The density of the powder can lead to overloading issues inside of the screener. Copper powder is so dense that it doesn’t take a lot to overwhelm the screen and kill the energy so a good level inside the screener is imperative.
