The drum screen is mainly used after the hydrapulper in the waste paper pulping production process. The drum screen is used to roughly select the crushed waste paper pulp, remove larger impurities in the waste paper pulp, and purify the pulp quality.

Drum Screen Work Flow

The slurry sent from the hydrapulper (mostly water and light impurities such as plastics and styrene foam) enters the cylindrical screen and is carried into the air as the cylinder rotates, and then falls down due to the action of gravity;
At this time, the spray water washes down the available fibers attached to the impurities and collects them into the pulp outlet through the sieve plate; the impurities are continuously tumbling, washing and discharged from the cylindrical screen while the spiral guide blades are pushing forward.The white water containing a small amount of fiber in the pulp outlet tank can be returned to the hydrapulper for reuse, and the impurities will be drained away.

The drum screen is a device used in the pulp impurity treatment system to separate impurities and recover pulp fibers. If you want to know more detailed information about the pulping machine, please send us an email for consultation. Our email address: wastepapermachine@gmail.com
