The sieving device comprises a rotating disc, a cleaning disc, a rotating disc driving motor, a cleaning disc driving motor, a disc and motor fixed support, a sieving device base, a blanking hopper, a baffling board, a ball-shaped powder receiving hopper, a non ball-shaped powder receiving hopper and a rotating disc support inclination angle adjusting component, wherein the rotating disc, the cleaning disc, the rotating disc driving motor and the cleaning disc driving motor are all fixed on the support, the support is movably connected with the sieving device base, the support can rotate around a connecting point, and the inclination angle of the rotating disc can be adjusted through the rotating disc support inclination angle adjusting component. The rotating movement and the slope type sieving are combined, the mechanization and the automation of the sieving operation are realized, the non-continuous problem of the single slope type sieving operating process is solved, the operating process is greatly simplified, and the sieving effect and the efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of powder screening, and in particular provides a rotary disc type screening device for spherical powder screening. Background technique [0002] With the development of modern science and technology, some special application fields put forward higher and higher requirements for the sphericity of powder materials. Although there are many ways to prepare spherical particles, the production of non-spherical particles (such as flake particles, irregular particles, and spherical particles) cannot be avoided during the preparation process. Therefore, how to realize the relationship between spherical particles and non-spherical particles Separation becomes a very difficult problem faced in practical applications. [0003] Regarding the screening of spherical powder, the inclined plane separation method is generally used at present. The basic principle is based on the difference in the force characteristics and mo...
