Definitions
- this function is a function which will have a value depending on the friction encountered by the vortex, and somewhere between 1 for a theoretical frictionfree vortex and +1 for a theoretical friction vortex in which all energy is lost by friction.
- this function n will be an intermediate value, say of 0.75.
- a plurality of separators at A of a type adapted to separate both gas and heavier particles from pulp suspensions may be as per the construction shown in our co-pending application Serial No. 425,942, filed April 27, 1954, now Patent No. 2,757,582, reference to which is hereby made.
- the incoming stock to be treated is pumped from a conduit 50 by pump 51 and pipe line 52 into the inlets 53 of the devices A.
- the accepted cleaned stock from these devices ' is" conducted,
- the curves 70 and 71 represent the results of tests made with apparatus of the size and proportions hereina above disclosed and with the stock to be treated intro-v quizzed to the device at a pressure of about 41 lbs. per sq.
