Abstract
Sposób przetwarzania masy celulozowej w celu uzyskania masy papierniczej, w szczególności do produkcji bibuły, w którym to sposobie masę celulozową zawierającą rozwłókniony surowiec celulozowy o stężeniu 4% poddaje się mieleniu i rozbijaniu pęczków. Sposób charakteryzuje się tym, że proces mielenia i rozbijania pęczków prowadzi się jednoetapowo za pomocą urządzenia do mielenia masy i rozbijania w niej pęczków, tak że podaje się masę celulozową przez wlot (11) pod ciśnieniem od 1,5 bar do 2,5 bar z prędkością od 500 do 2000 litrów/minutę; wprowadza się tarczę obrotową (40) w ruch z prędkością od 500 do 1000 obr./min; kontynuując proces przetwarzania, przy czym przy stwierdzeniu zbyt małej smarności wyjściowej masy papierniczej zmniejsza się odległość pomiędzy tarczami stacjonarnymi (20, 30) regulując pozycję drugiej tarczy stacjonarnej (30).A method of processing pulp to obtain a paper pulp, in particular for the production of tissue paper, in which method the pulp containing 4% defibrated pulp is milled and broken into tufts. The method is characterized in that the process of grinding and breaking the knots is carried out in one step by means of a device for grinding the mass and breaking the knots in it, so that the pulp is fed through the inlet (11) at a pressure of 1.5 bar to 2.5 bar with speed from 500 to 2000 liters / minute; the rotating disk (40) is moved at a speed of 500 to 1000 rpm; continuing the processing process, and if it is found that the lubricity of the initial pulp is too low, the distance between the stationary disks (20, 30) is reduced by adjusting the position of the second stationary disk (30).
