The works of up-flow pressure screen

Up-flow pressure screen is a new recycled pulp screening device. The device for the characteristics of impurities in recycled pulp is designed to up-flow 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.
up-flow pressure screen works:
Known impurities in recycled pulp of light impurities in the heavy impurities in two parts. Conventional pressure screen from the upper feeding, bottom slag, the severity of impurities through the entire pulp screen area. When dealing with chemical pulp, because the proportion of impurities in the pulp and the quality is generally greater than
Individual fibers, this structure helps to reduce impurities in the residence time within the device. However, when processing recycled pulp contains large proportion of this small light impurities, it will greatly extend the light impurities residence time in the device, resulting in a decline in efficiency and increase screening rotor with the sieve drum wear or damage.
