Excessive pressure and uneven materials on the screen surface of the circular vibrating screen: The distance between the circular vibrating screen and the feed end of the hopper is too high. When ore enters the circular vibrating screen from the hopper, the impact force is too , leading to cracking and fracture boxes and other problems.

The ore is the feed end of the circular vibrating screen, and the uneven distribution of the ore always runs to one side, and only half of the screens play a role in the screen, resulting in severe accumulation of ore and low screening efficiency.

Material residence time is too long: ore screening is slow, ore moving speed is too slow, resulting in excessive ore build-up on screen surface, and circular vibratory screening is operated under overload , resulting in rapid damage and tearing of the elastic coupling screen.
