ABSTRACT:
A vortical circulation type pulper has a bladed and channelled rotor and an annular bladed and channeled stator mounted in a side, or bottom, wall, the rotor and annular stator forming a truncated conical attrition interface with the small end receiving stock for passage through the interface to the large end and thence for discharge or recirculation. Rotor/stator clearance at rest, is about 15/1000 of an inch. The stator is provided with an annular, pattern of alternate, triangular acquisition valleys and bladed and channeled peaks, each peak having an acquisition edge in the path of the stock reduction, edges of the rotor vanes so that the stock is reduced by the scissors-like contact of stock reduction edges of the vanes with the acquisition edges of the stator peaks in a stock reduction interface until sufficiently defibered to enter the truncated conical, bladed and channeled rotor/stator attrition interface for further treatment and recirculation or discharge.
