Drum Screen

Name: Drum Screen

Model: AT1200-3000


Inlet Capacity:5-6%


Rotary drum screen is one of the main components of the continuous hydrapulper impurity removal system. It is suitable for the rough selection of tailing. It is installed after the pulper or impurity separator, and it is Heavy debris is screened out, reducing the load of subsequent screening equipment. During operation, the pulp advances along the equal-pitch spiral guide vane on the inner ring of the screen drum, and the good pulp and small impurities pass through the Ф8-Ф14mm screen hole to the pulp tank under the action of gravity; the impurities with larger geometric shapes are slid along the spiral plate track to the slag discharge end and discharged. The water spray device sprays a certain pressure of water in a fan-shaped plane to wash away the fibers on the impurities and dilutes pulp, so as to eliminate impurities to the greatest extent and reduce fiber loss. The general purpose of drum screens is to remove plastic skins.
