Medium thick refiner / high refiner

Traditional low consistency beating, pulp concentration 4%, or less commonly rely mainly on ridges around the direct effect of the fiber, at this point, the fiber is mainly by transverse cutting, silk, feather, fine fibrosis is very weak, the role of strong beating, pulp concentration in 6-15%. High consistency pulp, slurry concentration is usually 15-35%. Beating process, rely mainly on the pulp fiber internal friction, and make the fiber width and specific surface area increased, silk, feather, fine fibrosis significantly, and the direct effect is abate, indented to avoid less fiber cut or cut off.
