Abstract (en)

In a paper recovery process, a fibrous semi-liquid mass containing foreign bodies and clumps is advances through a pump housing with an inlet, a pump wheel and an outlet. The pump housing interior chamber incorporates a number of fixed baffles (7) separated from the pump wheel (4) by an interval (e) of 5-10 mm. The fiber cutting baffles are located radially around the pump wheel in the fluid out-flow zone (5).
