AI Technical Summary
In existing barite powder screening devices, small, completely crushed particles tend to slip during the screening process, resulting in small particles being mixed with large particles, which increases the workload of secondary crushing and ineffective work.
The system employs a conical screening box, a vertically vibrating screening trough, baffles, and a vibrating motor. Vibration drives the screening trough and baffles to form a trough-shaped screening chamber, preventing small particles from slipping. The baffles are adjusted by telescopic push rods to separate large particles.
It effectively prevents small particles from slipping, ensures complete screening of large particles, reduces the workload of secondary crushing, and improves screening efficiency and equipment utilization.
