The working principle and the structures of the screen

pressure curved sieve is a kind of the high efficiency working screen that working by the pressure, and it is make up with the sieve screen, the sieve case, feeding device and exit device.

The sieve screen is the key part of the pressure sieve bend screen. It is made by stainless steel wedge wire and support wire.

When the working pressure is 0.2-0.4Mpa, the wet material will be erupt from the exit device.
The wedge wire could become the knife edge, it could help to shaving the material to a thin layer, and make the fine material and water Evenly spread out.

Reading of the “shaving effect”. It will help to grading easily, Then all the screen should cleaned. The surface material will be expel from the dross hole, and the fine material will enter the stock outlet.

The working pressure must be 0.2-0.4Mpa, the higher pressure, the higher sieve efficiency. Inverse, the lower pressure, the lower siece efficiency.

At the first sieve process, it will content about 7% fine dry material, then sieve the starch milk.
10-11BX, in the thin pulp, the SO2 content will be about 0.035-0.045%
