Coarse Screen and Fine Screen

coarse-screen-and-fine-screenLast time we have talked about how M.C. pressure screen works, it’s a excellent machine to screen slurry. The five holes and rigorous inner construction can separate fine stock, tailings and heavy impurities. Mid Consistency Pressure Screen can play a role in both coarse and fine screen, which are two important processes of cleaning and screening paper pulp.

Coarse Screen

Coarse screen apply to screening the slurry from High Density Cleaner. This step is also called the first stage mid-consistency coarse screen. The fine slurry is discharged to coarse screen pulp chest/agitator from stock outlet, and the tailings enter Light Impurity Separator and Reject Separator to be further cleaned. Then it enters coarse screen pulp chest/agitator and mixes with fine slurry from coarse screen.

Fine Screen

Fine screen is basically known as fractionating screen. It can screening the short fiber, which enter the Inclined Screen to be thickened. Mid and long fibers enter Low Density Cleaner and other M.C. Screen to be cleaned and sizing screened.

How to Differentiate Coarse and Fine Screen

Coarse screen basket usually is hole, while fine screen basket is small slot.
Coarse screen is equipped with a heavy impurities pipe, while fine screen doesn’t need one.

Cultural Paper Making Line

Cultural paper machine line: Firstly, Raw materials are conveyed by Chain Conveyor into Drum Pulper for pulping. Then, High Density Cleaner helps to remove heavy impurities. What’s more, we need to improve slurry beating degree by using Double Disc Refiner. Eventually, the waste paper turn into fine pulp after a series of screening and deslagging and it will be conveyed into Headbox for paper making.
