Abstract
A method and an apparatus for determining the fibre length distribution by weight of a pulp and a method and apparatus for determining absolute consistency are disclosed. The fibre length distribution is obtained by dividing the flow of a pulp sample into two separate flows, fractionating each of the flows by a screen into a retained and a through fraction, the screens being of different mesh sizes, measuring the amounts of each of a selected one of said retained or through fractions and determining, based on the cumulative normal distribution relationship of cumulative retained fraction in % of feed to fibre length, the fibre length distribution of the pulp sample.
