The paper material is transported to the hydrapulper through the conveyor belt, and is torn and rubbed in the hydrapulper to realize the purpose of pulp crushing. The shredded pulp is separated from heavy impurities by the strong eddy current of the Purification Equipment. The pulp refiner will separate and broom the pulp fiber. The slurry after refining will screen impurities according to the volume size of impurities and different fibers. After screening, some water in the slurry will be removed by the thickener to improve the slurry concentration for subsequent treatment. The function of the thermal dispersion system is to heat and melt or soften some hot melt in the slurry, such as asphalt, hot melt adhesive, wax, etc., and then disperse the hot melt into invisible particles under the action of mechanical force to improve the appearance quality of the finished paper.
