How to remove fine particles impurity in waste paper

The raw materials of paper are mainly plant fibers such as wood, straw, hemp, and bamboo,etc. Waste paper is also called

“secondary fiber”, its main purpose is to recycle fiber to produce recycled paper products. However, there are many small particles

in the waste paper. How to effectively remove these fine particles impurities? and maximize the value of

resources?

In the traditional method of removing ink particles, metal impurities, and sand particles, the high and lo density cleaner

are usually used to remove metal impurities, sand particles, and ink particles out of the system, resulting in a low pulp yield.

The method to remove fine particles impurity in waste paper is that:one-stage low density cleaner, two-stage

low density cleaner, three-stage low density cleaner and four-stage low density cleaner.and the first-stage low density cleaner,

second-stage low density cleaner, three-stage low density cleaner and four-stage low density cleaner all include slurry inlet

head, fine pulp pipe, separator pipe, lower cone and nozzle.

Using the above method to remove fine particles impurity in waste paper,can ensure that the waste paper pulp meets

the cleanliness on the finished paper hanging surface, and improve the yield and pulp quality of pulping.
