Description

Technical Field

[0001] The utility model relates to the field of grinders, in particular to a copper powder grinder. Background Art

[0002] The operating principle of a drum-type copper powder ball mill (grinder) is as follows: Material enters the mill drum through a feed device. As the drum slowly rotates under the drive mechanism, the grinding media (steel balls) inside the drum are lifted to a certain height due to inertia and centrifugal force. Once the grinding media reaches a certain height, they fall vertically under their own gravity. The falling grinding media, like projectiles, impacts and grinds the material inside the drum, achieving initial crushing. This process occurs in the first chamber of the ball mill (if the ball mill has multiple chambers). The material is coarsely ground in the first chamber. After preliminary grinding, the material passes through a single-layer partition plate into the second chamber (or subsequent chambers) of the ball mill. These chambers are also equipped with grinding media (steel balls), but these may be of different size or have different motion states than those in the first chamber, providing further grinding for a finer grinding effect.

[0003] When the copper powder grinder is actually used, the copper powder easily sticks to the inner wall of the drum and cannot be discharged. Copper powder is expensive and it is easy to waste copper powder. At the same time, the copper powder cannot be discharged in time and clumps on the inner wall of the drum, which is inconvenient for subsequent cleaning. Utility Model Content

While the grinder drum 1 is rotating, the copper powder to be ground is added to the inside of the grinder drum 1 to grind the material and make the material ground more finely.
