Description

Technical Field

[0001] This utility model relates to the field of artemisia sand mill technology, specifically an artemisia sand mill ball adding device. Background Technology

[0002] The working principle of the sand mill is mainly based on the friction and collision of the grinding media within the grinding cylinder to grind materials. During this process, the motor drives the reducer to rotate, causing the media and materials inside the grinding cylinder to continuously roll, grind, and mix. Strong collisions, friction, and shearing effects occur between the material and the grinding media, thereby accelerating the grinding of fine particles and dispersing agglomerates. Simultaneously, due to the centrifugal separation effect of the rotor, the grinding media separates from the material. The finely ground material flows into the receiving container through the centrifugal filter gaps, propelled by the feed pump, while the grinding media remains in the mill cavity to continue grinding coarse particles in the slurry. After multiple cycles of grinding, the material particles can achieve the required fineness and particle size distribution range. The core of the sand mill lies in its powerful grinding capacity and effective separation mechanism, enabling uniform and fine material grinding.

[0003] During operation, grinding balls need to be inserted into the ball mill. Traditional ball-adding methods require stopping the machine and restarting it after adding the balls. On the one hand, adding grinding balls requires stopping the machine, which affects the efficiency of material grinding. On the other hand, stopping and restarting the machine increases the consumption of electrical energy. At the same time, different particle sizes of materials require different grinding ball sizes, so grinding balls need to be added into the machine regularly. Furthermore, it is not easy to adjust the position of different sized grinding balls in the ball mill according to the particle size of the material.

[0004] To address this issue, this utility model provides a ball-adding device for an abrasive mill, which uses the sieve holes at the outer end of the partition plate to screen the grinding balls, and simultaneously uses the screen mesh inside the sieve plate to screen the material and grinding balls, thereby solving the aforementioned problems.
