AI Technical Summary
During the screening process of graphite anode materials for lithium batteries, as materials are continuously added, a large amount of material tends to accumulate on the sieve plate, causing the sieve holes to become blocked, the screening speed to slow down, and the newly added material cannot be effectively screened, resulting in ineffective screening.
The system combines a material control component and a drive component. The material control component automatically adjusts the feeding speed through the feeding baffle to reduce the burden on the screen plate, while the drive component improves the stratification and uniformity of the material on the screen plate through reciprocating motion, ensuring screening efficiency.
It effectively avoids ineffective screening caused by sieve plate accumulation, improves screening efficiency and uniformity, reduces local material accumulation, and enhances screening effect.
