Drum Screen For Continuous Pulping System

Used with impurity separator to deal with larger geometric shape plastic, rubber, gravel, metal, film and other light impurities and heavy debris in the waste paper pulp.

Structure principle

Screen Drum is mainly composed with screen drum, box, gear adjustable-speed motor, spray pipe,etc. There are helical blade within screen drum, which has the conveying effect for impurities. The light containing with stock enter screen drum from inlet mouth, with the effect of gravity, fine pulp discharges with screen hole from fine pulp mouth. The light impurities was conveyed to screen drum tail and discharged by the helical blade within drum screen. Water spray system is installed in the two sides screen drum’s inside. On the one hand clean the slurry within impurities, on the other hand wash the screen drum and keep the screen hole fluent.

Advantage of Drum Screen

1. Reducer gear drive, smooth operation, reliable

2. Continuously variable transmission, flexible adjustment

3. As a coarse screening device, the screening area is big, low power consumption

4. Simple structure, convenient to repair.

5. Can guarantee high purity of impurities and less fiber loss, etc.
