Abstract

A fibre suspension (S) rheological property determination procedure has a rotor (8) pressure sorter with cylindrical sieve (3) with through (A) and overflow (R) streams with pressure impulses on the sorter housing wall (11) measured in two places to calculate the suspension consistency using a peak value Fourier analysis.
