Beating (refining),with simple equipment and complicated process,plays an important role in pulping line. The uniformity of pulp fiber often affects the paper formation and strength index.The reasons affecting Refining are summarized as follows.
In the process of pulping, double Disc Refiner often results in uneven wear of the discs in both refining zones, affecting the pulp formation and equipment stability.
Many refiners set a lower beating power, which is difficult to become slurry at one time. It takes a long time to repeat until the Post-slurry Chest or Semi-slurry Chest achieve the specified beating degree and wet weight index, resulting in excessive pulping of some pulp fibers and some fibers are not effectively beaten.
Some beating plates with poor impact resistance often have unexpected large-area broken teeth and uneven wear, which causes the discs to be scrapped in advance.
Alloys with lower hardness and stainless steel refining discs have better impact toughness, but because of the soft material, they tend to be passivated during use.
Leizhan company has many years of experience in producing high-quality Refiner. Welcome to contact us for more details. You can also get the whole set of Papermaking Machine.
This line includes Chain Conveyor, Drum Pulper, D Type Hydrapulper, Mid Consistency Pressure Screen, Double Disc Refiner, Inflow Pressure Screen, and so on. Paper pulp machine used to make waste paper (such as waste packing box,waste office paper and so on) turn to fine pulp for paper forming on the paper machine.
