Up-flow pressure screen of paper machinery

LSS series of up-flow pressure to the bottom of the screen into the pulp, the bottom row of heavy residue, the top row of tailings and slag in the up-flow light structure designed to effectively address these issues. Light impurities in the air and slurry to rise to the top of the natural slag discharge port, re-entered the body of impurities can be discharged the Ministry of Settlement in the end. On the one hand effectively reduce the impurity residence time in the screening area, reducing the possibility of recycling impurities and improve the screening efficiency; on the other hand to prevent the re-screening of impurities on the rotor and drum damage and prolong service life of equipment . Advantages 1. Very low power consumption: fine sieve power ≤ 5-8KWH / T paste, coarse screening power ≤ 5 KWH / T plasma, has reached and exceeded the international most advanced level (10KWH / T plasma). 2. Heavy weight of impurities into the screen at the bottom of cans, to prevent the rotor and the sieve drum wear and damage and reduce downtime. 3. Light impurities and air from the top end of the rapid plasma discharge port. 4. Screening efficiency, impurities in the pulp screen area to stay a short time, significantly reducing the possibility of recycling impurities. 5. The required low pressure into the slurry.
