Description

Technical Field

[0001] The utility model belongs to the technical field of corundum production technology, and specifically relates to a corundum particle screening device. Background Art

[0002] Corundum is a gemstone formed by the crystallization of aluminum oxide. It is produced in aluminum-rich, silicon-poor igneous rocks and pegmatites, and coexists with minerals such as feldspar, spinel, skarn, magnetite, and muscovite. The components contained in corundum are relatively complex, with a hardness of about 9 degrees, a hexagonal prism-shaped crystal structure, a glassy or sub-diamond luster on the surface, and obvious dichroism.

[0003] After searching, the Chinese utility model patent application document with Chinese patent authorization announcement number CN217830680U discloses a screening device for white corundum particles, including a box body, white corundum is put into a screening cylinder for screening, and the screening cylinder is driven to rotate by a rotating device. When the screening cylinder rotates, the screening cylinder is driven to rotate by the rotating device, and the larger particles after screening remain in the screening cylinder, and the smaller white corundum particles fall into the box body. When the driving device drives the screening cylinder to rotate, it drives the driving component to run synchronously through the synchronous motion component, and the driving component drives the vibration block to move when it runs. The elastic component makes the vibration block hit the screening cylinder during the resetting process, so that the white corundum in the mesh of the screening cylinder falls off.

[0004] With respect to the above-mentioned related technologies, the screening cylinder provided in the device is not convenient for flattening the white corundum particles, so that the white corundum particles are accumulated on the screen, and the white corundum particles cannot be effectively screened. Therefore, it is urgent to design a corundum particle screening device to deal with these problems. Utility Model Content
