Be incapable of removing stone, or the effect of stone-removing is not good. | Negative pressure is too high. | Lessen negative pressure, and clean sieve frame. | Inclination of sieve cover is too big. | Reduce the inclination. | Final separating area is not open enough. | Enlarge the separating area. | Sieve bursting. | Replace sieve. | Sieve blinding. | Replace rubble block, and clean sieve frame. |
|
There are too many grains in stone discharge outlet. | Negative pressure is too low. | adjust feeding. | Inclination of sieve cover is too less | incvease the inclination of sieve cover. |
|
Negative pressure increasingly goes up | Dust accumulates on the frame between air adjustable board and screen. | clean sieve frame. | Dirty air enter it. | improve surrouding | Rubber balls within screen frame damage. | replace new rubber ball. |
