Description

Technical Field

[0002] In the manufacturing process of lithium battery positive electrode materials, a sand mill is used in the grinding process. The discharge port of the existing sand mill, especially the horizontal grinder, is located near the main shaft of the grinding cylinder, and the discharge port is located on the end wall of the outer cylinder along the axial direction of the outer cylinder. Since the internal material flows along the edge of the cylinder, it is very easy to be blocked; and the size of the sand milling medium addition port of the sand mill is not large (about 6.5cm in diameter), and the size of the sand milling medium is too small (about 0.1mm-1.0mm in diameter). When the sand milling medium is added by a funnel, due to its small volume and mass, the free fall speed of the sand milling medium is low and the feeding hopper speed is slow;

[0003] At the same time, because the amount of sand milling media added each time is very large (about 1.2t-1.7t), the stacking density of the sand milling media in the hopper will be too high when adding, and in the grinding process, there are conditions where multiple sand mills need to be added at the same time; therefore, the current method of adding using a hopper is too inefficient and can no longer meet production needs.

[0004] Therefore, the utility model designs a sand mill medium adding device for a sand mill. Utility Model Content
