Kinetyka rozpływu sieci wiążącej w granulowanym złożu

In the paper, effort was made to determine the spreading kinetics of binding liquid supplied to fine granular mass in a cylindrical apparatus and to find its relationship with the granulation process. At predetermined intervals during the wetting process the indicator (ethylene glycol) was added in a form of Dirac impulses and then the migration of liquid within granular mass was determined on the basis of the indicator content in a sample measured fraction. The measurement method was based on the extraction of indicator from a dried fraction of granulated material (silica flour) using CC14 and then applying the FTIR spectro-scopy.
