Paper Machine Formation Section

Paper machine forming section is a part where paper pulp fiber is formed into web of paper. During production process often due to changes in the performance of the pulp or beaten quality fluctuations resulting in the paper material water changes. So how to deal with the malfunction of paper machine forming section?

Paper Machine Formation Section

1. When the paper water filtration rate slows down, you can improve the concentration of the wire, the treatment method is appropriate to reduce the amount of diluted white water, in order to maintain the same quantitative, should be appropriate to increase the amount of slurry control valve opening. This adjustment, the headbox weir pool water level is reduced, the pulp speed has also been reduced, the wire backwards.
2. In addition to reducing the amount of white water, but also increase the amount of water (add water into white water pool below wire) instead of white water to reduce the amount of fine fibers in paper, so that the paper filter performance improved. In this way does not change the headbox head, this method often used in paper machine which adopt full flow type headbox.
3. When the water filtration rate is too fast, then the opposite method of operation to reduce the concentration of the wire. Some paper machine in the slurry flow system connected to the refiner machine, wire paper filter water fluctuations can be adjusted through the refiner to control the paper evenness on the paper machine.

Leizhan paper machine has high quality, our product based on 37 years experience and strict inspection on every production step, can withstand rigorous testing, can avoid some common faults during operation, has longer service time, don’t often replace the wearing parts, save maintenance costs.
