| 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. |
