[0002] The ball mills manufactured nowadays are all large equipment with high platforms, so unloading the balls has become a troublesome problem. If the balls are unloaded from the mill door, safety issues may arise on site due to the high platform height.

[0003] On the basis of the ball mill, the addition of a specially designed ball unloading bucket and ball screening device can effectively help the ball mill unload and separate the balls, complete the steel ball screening work while avoiding safety problems on site, and improve work efficiency.

[0004] To this end, we propose a ball unloading and screening device suitable for ball mill. Utility Model Content
