Drum screen is usually installed after pulper or impurity separator. It can screen out all kinds of light or heavy impurities whose geometric shape is larger thanΦ10mm, such as plastic, rubber, sand, stone, metal pieces, film, etc.
While the screen drum rotating, pulp will be conveyed forward. By gravity, accepts and tiny impurities will enter the vat throughΦ8-14mm screen slot; larger impurities retained on screen plate will be pushed forward to the end by screw flight. The fiber adhered to the impurities will be washed off by water ejected from the fan nozzles in order to prevent fiber loss.
Simple structure; safe and reliable in operation and high efficiency in coarse screening.
Used with the hydrapulper system to screen out coarse impurities and improve the purifying efficiency of process.
Main technical data:
Screen slot diameter (mm)
The capacity may be different according to different pulp variety and concentration.
So the capacity in the above chart is only used for choosing the model.
