Document Type and Number:
Japanese Patent JP2923528
Kind Code:
B2
Abstract:
In an apparatus (10,100,300,400) for refining a low consistency fibrous slurry, which includes a plurality of refining zones (38,40; 188,128; 324,334; 411,413) within a casing, the improvement comprises providing a unique discharge flow path from each refining zone to a respective unique discharge line (56,58; 130,142; 308,310; 411,413) out of the casing, and means (57,59; 141,143; 344,346; 432,434) for differentially adjusting the flow rate in each discharge line. In accordance with the preferred embodiment of the invention, a divider (42,132,340) is provided between the casing and the rotor member, thus dividing the discharge between the two refining gaps, into two separate flow streams. The first and second gaps are monitored in any conventional manner. Under operating conditions, the flow control valves are adjusted for combined flow from the refiner casing as required by the production demands. However, the relative positioning between the two valves is adjusted until the refining gap measurements show equal gaps (within a pre-established tolerance) in the two refining zones.
