Abstract
A method and apparatus for determining the consistency of pulps by squeezing the pulp in a press and registering the pressure required to initiate the flow of water from said pulp, said pressure being indicative of the consistency of the sample.
Claims8
An apparatus for determining the consistency of a pulp having a consistency of between a 15 and 55% comprising;
- a container, a foraminous support means in the bottom of said container adapted to support a pulp sample and permit water from said pulp sample to pass therethrough, a water outlet from said container for water squeezed through said foraminous support means, pressure means for pressing a pulp sample in said container against said foraminous support and squeezing water from said pulp sample, and means for registering the pressure applied to said pulp sample at the initiation of flow of water through said outlet.
A method for determining the consistency of a pulp comprising placing sample of said mechanical pulp having a consistency of between 15 and 55% into a container, supporting said sample of pulp on a foraminous support means gradually increasing the pressure applied to said pulp until water is squeezed therefrom and through said support, registering the pressure required to initiate flow of water through said foraminous support thereby to obtain indication of the consistency of said pulp sample.
