It is mainly used for separating long and short fiber during pulp screening. It can be used as pulp screening equipment by controlling the rate of discharging rejects.

Design features:

Under the pressure, the pulp enters into the screen cylinder along the tangential direction from the bottom. The heavy impurities are discharged from the collecting box of heavy impurities on the bottom of the equipment so as to prevent the rotor and screen cylinder from wearing and being damaged. The pulp flows into screen zone. Affected by the different pressure between the inner and outer of screen cylinder as well as kinetic energy, short fiber flows into the accept zone through screen cut. Affected by the self-washing created by the rotating of the rotor, the long fiber and light impurities held up by screen cylinder are discharged through the pipe at the top of the equipment, which results in separating the long and short fibers as well as improving the efficiency of screening.
