Canadian Standard Freeness Tester

Beating pulp fiber provides effects such as fibrillation, generation of fines, reduction of fiber in length and volume, etc. depending on the beating method and time. As a result, various physical characteristics of the paper are affected in addition to the fluidity and drainage performance on wire cloth. Beating has a significant role in the paper manufacturing process, and the resulting drainage performance needs to be evaluated. Some of commonly used evaluation methods involve use of a Canadian standard tester and Schopper-Riegler freeness tester.  In those methods, a certain amount of suspension liquid is filtered through a screen plate or wire cloth, and the white water is sampled from the funnel side tube, whose amount is measured and used to determine the beatability. This tester uses a screen plate for filtering suspension liquid and is provided with a cock to be operated to start drainage. Thus, it eliminates differences in the result when different operators are involved, yielding high accuracy.
