Pulp

The main technological parameters to be controlled in the pulping process are the concentration, time and concentration of the slurry. The concentration and time of the pulp determine the degree of the feed, and the concentration of the slurry is the basic condition for the next step.

Refining

The main technological parameters to be controlled in the grinding process include slurry throughput, refining power and refining concentration. Because the real time mixing slurry makes the amount of long and short fibers change greatly, and affects the outlet pressure of the refiner at the same time. This needs to change the flow rate, and control the slurry to pass through therefiner to control the outlet pressure of the refiner.

Slurry

Now the process of high speed paper machine are real-time mixing, are generally divided into upper and lower slurries. The upper slurry is made of long staple fiber and staple fiber, mostly staple fiber, which makes the upper surface feel smoother; The lower slurry is made of long fiber, staple fiber and paper, and the long fiber and the damaged paper are in the majority, so that the produced toilet paper has better pulling force. The main technological parameter to control the slurry mixing process is the flow rate of each slurry line.

Dry

The drying system includes the steam system of the dryer and the hot air system of the hood. The steam system mainly heats and eliminates the condensate in the dryer. Therefore, its main technological parameters are the steam pressure in the cylinder and the steam flow through the dryer.
