description1
It is mainly used for continuous beating of chemical wood pulp, mechanical pulp, and waste paper pulp; it is a continuous beating equipment for coarse and fine grinding of pulp in the papermaking industry, and can also be used as pulp slag.High-efficiency deconsolidation equipment for re-grinding and re-pulp. Equipped with various tooth-shaped grinding discsand automatic control system, it can achieve constant power or constant energy consumption and stable effect.
The refiner has two abrasive sections. By the inclination angle of abrasion pattern, four abrasive plates are fixed, two left and two right. Two left plates are fixed on inner wall of machine shell and inside of rotating disc and two right plates are fixed on outside of rotating disc and moving pedestal, forming two abrasive sections (see drawing for installation instruction). Stock is conveyed to abrasive section through inlet pipe. After beating and refining, pumped out from the abrasive section and flows into shell, at last discharged from outlet pipe.
