Retention (Dynamic drainage jar No.2586)

It is widely known that the retention of the filler and fines rapidly drops as the running speed of the paper machine increases. This equipment is designed to reproduce the turbulence condition on the paper machine's wire part and to measure the retention of the filler and fines. An agitator is incorporated to apply a sudden shear force on slurry to have it deposited as a mat on the wire installed in the pulp tank. Then a certain amount of white water is sampled
From the first portion that has passed through the wire. After accurate measurement of the white water, the solid portion is filtered through filter paper and dried, and then the amount of the ash content is measured, based on which the OPR (retention of fines and filler) is calculated.
