The working principle of pressure screen

 Pressure screen for impurities in recycled pulp is designed to up-flow characteristics of the structure can be widely used in a variety of waste paper pulp and coarse sieve, coarse screening and before the pulp screening machine with unparalleled performance and the good work reliability is a variety of domestic pressure screen for recycled pulp processing replacements.
Pressure screen adopts to take the bottom of the slurry into the bottom row of heavy slag, slag top row of light-up-flow structure design, effectively solve the above problems. Light impurities and paste the air naturally rise to the top slag discharge port, heavy impurities into the body can be a settlement in the end portion discharge. Thus, on the one hand effectively shortening the impurity residence time of the screening area, reducing the possibility of impurities circulation, improve the efficiency of screening; heavy impurities on the other hand to prevent the rotor and the sieve drum damage and prolong equipment life.
